I'm still learning about 2012 Olympic stamps and the Olympic philatelic traditions, but will just write briefly tonight that the U.S.P.S. is missing out on an opportunity to maintain several consecutive Olympiads of original and beautiful five-ringed designs (some of my personal favorites include Robert Peak's iconic Olympic stamps for 1984 in Los Angeles as well as Bart Forbes' designs for 1988 and 1992, the latter released during the 1990 U.S. Olympic Festival in Minneapolis/St. Paul).
What Olympic stamps are due out for other nations in 2012? I'm just starting to research this. If you see one you like, or loathe, please send me a link.
