Here are some pics of an Original Western Union Telegram and Envelope. I thought some of you would like to see it and read a description.
The paper is a yellowish color and the consistency of newspaper. I thought it would be thicker from the pics I have seen. I found this in a local Antique shop mixed in with old photos and postcards. I also found old stamps including the Italian stamps from the mailing wrapper.
There is nothing printed on the back of the Telegram itself. I have seen pics with ads for Western Union on the backs, like what is on the back of the envelope but more elaborate.
Telegram is 8"x5 3/4" (more usual size is 8"x6 1/2") Envelope is 6 1/2"x3 5/8"
