One of the most famous stamp collecting women in history is Amelia Earhart. The sale of her own stamp “souvenirs” helped fund her work. When her plane went down in 1937, the nose cargo compartment contained over 5,000 souvenir covers that her supporters had paid for (the idea being that these autographed treasures would be delivered when Ms. Earhart returned from her journey).

“What is a cover?,” you ask. While it would be far sketchier for me to make you wait until I made a COVID card about covers, that may never happen. So, I’ll tell you. They are stamped envelopes. Big deal, right? It can be to stamp collectors. While a cover can be the envelope you put Uncle Norman’s birthday card in, it would probably only be desirable to collectors if you used a rare stamp or if Uncle Norman was famous — or if you are famous (and, perhaps, dead). Covers are typically cancelled (they’ve actually gone through the mail and the stamp cannot be reused for postage), but they don’t have to be. I’m pretty sure that only cancelled covers are considered valuable. And now that I’ve written more about this than Amelia Earhart, I’ll stop. Maybe there will be a Cover COVID Card in the future.
