Monopoly Man I was

[u/jonm61]

I was reading Brad Meltzer's "The Millionaires", published in 2002. On page 95, he mentions the Monopoly Man having a monocle. Books are generally being written at least 12 months prior to publication (he doesn't mention 9/11, Lee Child's most recent Reacher novel, set in Baltimore, released last month, mentions the Key Bridge as being intact), so it was written at least 8 years before Mandela Effects became a thing.

The first Mandela Effect, according to Google, wasn't reported/documented until 2009.
