One Reply to “American Topical Association: Philatelic Errors in Topical Collecting”

  1. Mr. Betanov,
    Thank you so much for sharing your passion in EFO’s. This gave me new ideas on arranging stamps I own that depict many of my interests. It seems you put a lot of research into an album page and that is really a fun thing. You are correct. I now look at stamps differently. Therefore, your talk has breathed new life into my collection and I appreciate that. Thank you for your presentation.
