Stamp Collestion. Western union 1940 5 cents revenue stamp
Western Union did not issue their own postage stamps. During the era you specified, they used what are called revenue stamps. These were special stamps used to pay specific fees, in this case, the cost of sending a telegram.
Here’s an image of a 1940 Western Union telegram 5 cent revenue stamp:
The stamp itself wouldn’t have been used for postage, but rather affixed to the telegram form itself as a way to show the telegram fee had been paid. These stamps are of particular interest to collectors because they are tied to a specific telegram and often have the date and location the telegram was sent from written on them.
