The most common picture of Carl Gauß depicts him wearing a black velvet cap. It is a pretty cool-looking cap, and I wonder if there isn't a small opportunity to sell math people black velvet caps like Gauß.

The same opportunity does not exist for Euler, whose most common depiction appears to have just gotten out of the shower, and to be wearing a bathrobe and to have a towel wrapped around his head.\
