The US Postal Service recently issued a little bit more information on the John Lennon Forever stamp, part of its Music Icons commemorative series.

The stamp will be issued on September 7 in New York City, and with more details of the design being made public there’s been a bit of a surprise twist: there will be not one, but four different stamps in this issue.

As you can see above, because the stamp will be issued in a pane of 16 (with the stamp pane made to look like the sleeve of a 7″ record – which is kind of cool), the stamps in each row are to be treated in different gradient colors, creating four different varieties.

The colors on the stamps in the first row change from light orange to red; the second row changes from red to light purple; the third row is light purple to dark purple; and the fourth is dark purple to blue.

The image on the reverse of the pane is the black-and-white photograph taken by Peter Fordham at about the time of the Imagine album release in 1971. It is of Lennon at his white piano. His signature is in white above, and there’s a Music Icons logo bottom left.

The John Lennon stamp was designed by Neal Ashby and Antonio Alcala was the art director.The US Postal Service press release is here.
