I have many First Day Covers. I'm happy to list topics at the request of fellow members. Am a Life Member of the American First Day Cover Society since 1982, a non-profit organization dedicated to the advancement of First Day Cover collecting. Our bi-yearly auction (www.afdcs.org) is open now and will end June 2nd - you do not have to be a member to bid! The bids are "closed", meaning you bid what you want to pay, and bids are not disclosed. Winners are notified at the end. If you questions about First Day Covers, please feel free to ask me!
