COMMENT: There has been a lot of discussion about this poster: some say it is an original...some say it is a reprint. The reprint theory is supported by the fact that all other posters from this concert tour were a slightly lighter shade of red. However, the Cologne poster was produced by a different printing company. A strong argument in favor of the original is that the paper is clearly very old and these types of paper were used for posters in the 1960s. Another argument in favor of the original is that in all the Internet discussions no one was able to provide a verified original poster which is NOT looking like this one.
