Karl spake: << we've been using them for years in Oz.. Long after the letter has decomposed in the letter box,the stamps remain >> That's good to hear, but I was wondering about the sheets of Masters of American Photography stamps being produced by the USPS. I recently came across letters my father had written to his sister during WWII and the stamps are as good as the day they were cancelled. I don't doubt that the stamps (in sheets with adhesive backing) will last when affixed to a letter, but will they separate from their backing when, for example, they are framed and stored vertically? The gummed variety of stamps didn't have the issue of backing material to be concerned with--just cockroaches and other bugs being attracted to the glue. Should they be given the same archival considerations as a photograph, or are there other issues to be concerned with?
