Question

When a new stamp is issued the stamp collectors buy some and use them to mail themselves for collection what is the envelope called?

Answer 1

This type of envelope is called First Day Cover. First day covers are letters that philatelists collect. On the day when a new stamp is issued, stamp collectors buy those stamps, stick them on the letters and post them to their own address; when this letter reaches their home with the postmark and the date, they preserve it in their collection. This letter is called a first-day cover. They’re never opened. They are just preserved.
