Where can i sell my vintage original optometry drawing?

[cadby]

I have about forty original optometry drawings and original patent drawings from 1938 and I'm looking to sell them. Some are of the eye some of the brain and skull. Any help or advice would be great. The artist or dr. Is russle collier if that helps.

Ebay would be the obvious answer, but check into Etsy.com.
People who use Etsy specialize in selling only either vintage or handmade items (as per their guidelines).
As for non-online sources, I don't know.
