Found a French web site selling some Bob photos. Problem is it's in Euros, and an 8x10 ain't cheap. By their calculations, it's $17.70. Nice 1932 Hurrell though (I think I'm turning into a Hurrell nut).
Go check it out
They have other photos for classic actors & actresses as well.
If you want to cheat, get a high res photo of one of the three pics over here (the top left one). Go print it on your own! Another high res here of the Letty Lynton Hurrell.
