Hard to believe it's even possible but Sesame Street is celebrating their 50th anniversary this year.

In celebration of that celebration, the United States Postal Service will be issuing postage stamps featuring sixteen of Sesame Street's most popular characters.

Here is what the USPS website has to say about the stamps:

Sesame Street

The Postal Service honors Sesame Street as one of the most influential and beloved children’s television shows. For the last 50 years, it has provided educational programming and entertainment for generations of children throughout the country and around the world. The stamp art features photographs of 16 Muppets from Sesame Street — Big Bird, Ernie, Bert, Cookie Monster, Rosita, The Count, Oscar the Grouch, Abby Cadabby, Herry Monster, Julia, Guy Smiley, Snuffleupagus, Elmo, Telly, Grover and Zoe. Art Director Derry Noyes designed the stamps.
