Raise hands if you have seen this irl or used this

It says 1999, but I haven't seen it 😕
Am I too old or too young?

Seen it, sent it. Many many times. Old times....😊

We used to have assignments in school for writing a letter with each form of postal communication - postcard, inland letter, international inland letter, envelope etc.

My dad was posted out of state for long periods. My mom used to ask us to write to him in these. Fun times.

I was in boarding school. We would write letters home every two weeks on these letter cards. My parents have some saved.

They are called inland letters

Seen them , posted them and also used them

Not this one, but I've used this type of letters
