Something about the 52' Topps Adcock that is driving me nuts

[Brianruns10]

So I've been eying the '52 Adcock for my Topps set recently, and for each card I buy I like to research it a bit. And in reading up on this card and the player, I found something unusual, that has me stumped. I'm sure there is a simple answer, and this may be a dumb question, but I'd appreciate help, 'cause it is driving me nuts!

The issue is this: in '52 Adcock was still with the Reds, and the Topps card reflects this. However, I found the black-and-white photo used by Topps as the basis for their color image, and his hat has a big fat M for Milwaukee on it! The two poses are identical, except Topps erased the M and put a C on his cap, and inserted a background.

So how can this be that Topps would use a photo of a player wearing the hat of the team he had not yet begun to play for? Obviously they didn't time travel to get it, so what is the answer? Had Adcock already been traded by late '52, and photographed in his new Milkwaukee regalia, and Topps was "backdating" the card (along the lines of their practice of not having 1952 stats on the card, so they could resell the cards past '52). Or does the M stand for something other than Milwaukee, and it's just a coincidence? A third solution...? My thanks to whoever clears up this puzzle for me!
