I agree with David (cycleback) that the basics should be checked. Use a black light. Use a microscope & see if it's photo engraved. Some cards were photo engraved for many years after 1930, but the ink will have a distint look around that time period. Experts like David, or a (self proclaimed) semi expert like myself could help. I bought one of those fifty dollar "Digital Blue" microscopes, & they work great for taking 10x, 60x, or 200x digital pictures.
