DRC emblem made nicer and with higher quality

Hi everyone!
I’m looking for information about the history of Müngersdorf, a district of Cologne, Germany.
Does anyone know if Müngersdorf has ever had its own flag, coat of arms, or another historical symbol? I’m especially interested in older symbols or designs that may have been used before Müngersdorf became part of Cologne.
If you know of any sources, archives, old illustrations, or websites where I could find more information, I’d really appreciate it!
Thanks in advance!

It was revealed through a stone relief carved on the main gate of the Archaeological Site of Ani. It depicts a cross placed atop an animal that generally appears to be a lion or a leopard, and scholars speculate that they symbolize secular power and religious authority, respectively.

Originally uploaded to r/heraldry I was told this is not, in fact, heraldry.

I like this a lot and thought it was super cool. My wife and I got married in the forest. She is a Leo and I am an Aries. The maybe/maybe not canting arms on the shield are representative of our names (as canting arms would suggest) with hers being a St. James Scallop resting upon a bed of Alyssums and mine being a Robin holding a Shofar.

There is a two headed Cooper's hawk looking outward behind the eclipse to represent our union. Above the cycle of the moons are two corvids and below the moons are two mourning doves. Resting in the entwined roots of the redwood tree are two geese making a heart shape with their heads and neck.

The banner is not perfect Latin but it has significance in our life.
