In the early days of the mail, letter sheets were the common way to send letters. Messages were written on paper that was folded and sealed. Some postal authorities would charge by the amount of paper used, so using an envelope would make mailing a letter more expensive. As these laws changed and envelopes became the common practice, letter sheets fell out of favor but were still used on occasion in the 1900s.

  1. They make an especially interesting collectable because the correspondence remains with the identifying indicia on the face, just as with postal cards. It’s also satisfying to easily complete the collection of this format.

  2. There was another such letter sheet used by military dependents to write to military personnel stationed overseas during WWII, wasn’t there /

  3. I just found one amidst my stationery and wrote an old friend who will get a good laugh and lump in her throat from nostalgia. 😊

  • Be nice and remember, we are all here to collect stamps!
