the Wilton t-shirt pan from 1979. I've tried ebay, but I don't really want to pay over $50... If anyone has one that they are willing to sell, please contact me email@example.com
This is a great website for cake pans and other goodies. I have ordered things a few times with no problems.
Wow! That pan is pricey these days.
I have to say that a t-shirt/jersey cake is one of the easiest to cut/create from a sheet cake. I do that most of the time because I require a shirt with more servings than the Wilton pan provides.
I run off a photo of a shirt from the internet, enlarge it, place it on the sheet cake, and cut it out. I usually wind up making a shirt body and then adding "sleeves". I torte it/them, fill, and ice.
Not exactly the way I do it, but these might help if you can't find the pan:
