I am biased towards the Los Angeles 1932 Olympics logo since it is so art deco and the font appears to have done by hand. I also live in Los Angeles.
The 1932 pool is still with us but quite modernized now. I am thinking of putting on a swim meet there next spring. I have to work out the details with SPMA and Clay Evans. Overall I like the Moscow logo a lot though the star should have been yellow to represent the Olympic flame.
As for the 2012 London Olympic logo; what were they thinking?
