Noticed this card a couple of days ago and didn't see a previous thread about it.
Despite Durocher being the Giants manager, the artist drew him in Yankees uniform colors. And doing an internet search, Sterling auctionhouse noticed it as well, but didn't call it an uncorrected error. They just listed him as the Yankees manager.

While most of the Yankees players are drawn in pinstripes, the jersey/cap coloring is the same on the few that are shown in gray jerseys. Giants are mostly drawn this way, with a reddish piping around the neck and in the NY cap logo:
1950 Bowman - [Base] #65 - Dave Koslo
