Next year, the Royal Mail in the UK will launch a stamp program that celebrates classic British album covers. The first class stamps are designed by Studio Dempsey and show a vinyl record sliding out of each sleeve.
Here's a bit from Creative Review where we found this:
Deciding what album covers to include was no easy task. Royal Mail tell us that they began the process by trawling through various existing polls of Greatest Album Covers. They also enlisted the help of editors from various leading UK music publications along with graphic designers and design writers who were asked to list the most significant album sleeve artwork used on records by British artists. The final selection of ten sleeves (which perhaps oddly doesn't feature one of The Beatles' album covers) will appear on a set of 10 stamps that will launch on January 7, 2010 - and the stamps will be uniquely shaped, as shown in these images, to accommodate a glimpse of a vinyl disc poking out of each record sleeve.
