1940s Mickey in general (not just in Sorcerer's Apprentice garb) I think is my favorite look, very classic and quintessential, although his art style in some cartoons in this decade was a bit inconsistent. Also partial to the 1983, as it seems to be the most similar to 1940 Mickey. I do however have a soft spot for pie-eyed Mickey (1929) and decorated my bathroom in this style.
