Pre-stamped postcards
Many postal services released "official" postcards, usually pre-stamped, with a logo to commemorate a specific event or cause. Not to be confused with First Day Covers, these envelopes are not tied to a specific stamp.
Right now this page is incomplete. Please e-mail me with pictures and information of any additional pre-stamped envelopes you have. Pre-stamped envelopes can be found on our envelope page.
I don't have any images yet, but will work on this page soon. In the meantime, send me things to put on it!
