I collect antique medical illustrations from the 18th and 19th century. My collection is small, mostly because the really beautiful pieces are usually quite pricey. For a more affordable option, Transmission Atelier is a fine art printer in Chicago that also reissues antique medical, religious, mythology, and natural history illustrations. They've picked some fantastic pieces to reprint. I haven't seen Transmission Atelier's work in person, but they describe their products as "extremely detailed limited edition digital pigment prints." Small prints (8" x 10") are $49.99 and the large ones (16" x 20") are $119.99.
