I googled Casa Rosso and Club 26 and it lead me to a club that was Run By the Mafia (Ties to Meyer Lansky) that was in the Amsterdam Red Light District in the 1970's. It burned down in 1984 and has a lot of mob history.

Its unfortunate that most of what I found is in Dutch, so I couldn't read it, but check out this picture!!!!! What a match for he logo !!!!!
