Original design by Luis Peiret
Modified design
It seems as though Madrid is bidding for the 20020 Olympics, not the 2020. The original design makes it more obvious that it is M20, but with the circles being cut off, you lose the communication. Also, the rings have had a mishap as the usual Olympic logo is blue, yellow, black, green and red, and here the black is misplaced with purple. It has a more Spanish feel, and a bit brighter than traditional ring logo, but does it really work as a contender? I'm not so sure.
