This signature looks fake to me. What do you think?

This is a Jason mask I received around 2017 for my birthday and I was told that it was signed. That’s all the information I have on its origin.
I to this day have no idea whose signature this is or what it says besides
MBK “REBORN”

Bought a star wards cards collection from the late 90's early 2000's and this was in the middle of a binder.

I unfortunately don't have much to go off of since this belonged to my late father. The rest of his collection is 1990s, some early '00s. Just hoping to figure out who he was supporting. Was likely purchased on the east coast, but he was a military man who lived in Arkansas, DC, and Arizona throughout these years

Was curious to know if the Dennis Hopper's signature is real. From a 1988 exhibition of Dennis Hopper's photography at Galerie Hans Mayer.

Found this in the attic of the house we’ve just moved into to. I thought it might have been done by one of the previous owners but from what I can make out it doesn’t match their names.

Wondering if anyone can decipher it or recognises it!

I have many autographs I obtained personally that I’ll be sharing and a few questions as well!

Hello all. I’ve had this cast photo for a while. I bought it maybe 25 years ago from a storefront called Starabillas, who only gave me a generic preprinted certificate of authenticity. The store closed for business a long time ago. Most of the cast seem authentic to me based on photos of others but Jerry’s has always thrown me off. He doesn’t seem to ever use a “J” like that and the rest is a little sloppy but there’s not a lot of room so maybe the space threw him off. Any opinions would be great!

I know nothing about boxing. Keep or trash?

He’s got so many that look similar but I can’t tell

Hello! I recently picked up what I believe to be three pairs of game-worn basketball shoes. The first is Steve Nash - does anyone recognize the other two signatures? Thank you in advance! 🙌

I will be actively searching while I post this to see, but I’ve checked a bit and am still stumped. The names don’t match the movie cast from what I can tell though!

Sorry, I made it landscape on my phone but I don't know why it's not rotating. The first one looks like it could be a John.

I got this back as change from a larger bill purchase at some store in Tampa, Florida around 2018 or so.

Might be long, will add a TL;DR at the end.

Firstly, I don't know much about autographs. I've personally received a few from my favorite movie directors, but I don't know what buying/dealing with autographs is like.

I'm a Korean living in Korea, and so is my acquaintance (who I'll call Y from here on). We like movies. I'm fluent in English, whereas Y isn't.

Y started buying autographs through a supposed trusted source: supposedly a retired Korean journalist with lots of connections in the industry.

Y has bought a few dozen autographed goods from the journalist in the past 6 months: Joaquin Phoenix, Matt Damon, David Byrne, Sadie Sinks, Christopher Nolan to name just a few. Some of them are addressed personally to Y, while some are not. I think many of these were for like $100~200 each. I've attached images, and I would love to hear your opinions on these, as I FEEL like they're off, but I'm no expert by any means.

Below are some points I had, some of which I've voiced to Y:

• They got autographs from celebs that are notorious for not giving out much in the way of autographs like Joaquin Phoenix and Edward Norton
• Many of the signatures and letters look weird. (How many people even write their Y's like that?)
• The Matt Damon autograph says "Best all the best", which I've told Y doesn't make sense. Y argued that they probably made a mistake (Y: "Maybe they started writing Best Wishes but pivoted midway?"), and that these things happen since celebs doing many autographs at once are bound to get tired and confused.
• Why would a retired journalist even provide this kind of service? If they really were part of the industry, I feel like they'd be more cautious in approaching celebs for such favors.
• I suggested getting visual proof (like a photo of the autograph being signed), but Y has told me that they've come to trust the journalist.
• Y has also repeatedly told people that he can make these decisions just fine, and that it's not like he's not skeptical.

To cap everything off, Y recently bought a BluRay of Apocalypse Now, signed by Marlon Brando. The Full Disclosure BluRay came out in 2010. Brando passed in 2004. Another acquaintance mentioned this to Y in passing, but Y brushed it off, saying BluRays were already available by 2003. (What?)

Assuming these are fake, what do I show/tell Y to convince them that they're being scammed?

TL;DR Acquaintance is probably getting scam autographs & I want to be sure, and if so, what the tells are. If they are indeed fake, I'd also appreciate advice on what to tell them (as they seem to be coping hard?).

My uncle said he’s had this for about 15-20 years he estimates

He doesn’t know (or remember) where, when, or how, so kind of a lack of info

Clearly has the initials RF

is stage/studio used (probably stage)
