I'm looking for an authoritative price guide for postage stamps, primarily US stamps from prior to 1960, similar to the Overstreet guides printed for comic books. There are a number of such stamps I would like to look up. Online would be great, physical guides that need to be purchased would be fine too. Thanks in advance.
