I did some double-checking and I did find that Jay Robert Nash had the photo in his Encyclopedia of Organized Crime, published in 1992. The Davis book was published in 1993 and as far as I know was the second to publish it. If you know of earlier sources I would appreciate the names as I have almost every Mafia book there is that has been published in English (and I have several Italian and German titles too). Regarding Nash, he was known to put out false information in order to catch plagiarists.
