I have one of those 'Neapolitan School of Music' ones, with the lady playing the stringed instrument on the back. There are quite a few of them about in UK. Some don't have the transfer on the back. Mine has the name 'Neapolitan Patent Mandolin Company' on the label. Hoyer used to make an archtop guitar-shaped mandolin, and I've seen other makes.
