Information Sought - Hitler Hate Club Badge

Does anyone have further information about the "Hitler Hate Club"? This badge crops up now and again online (eBay, militaria shops) and it would appear a fair few were issued but finding any information about the club (when it started, who started it, etc) is proving immensely difficult. There must have been some marketing of the club but I've drawn a blank so far.
