I've seen it before, of course, but totally, totally, totally forgot about it . But, if there's a part 2 to your article, I have more information that I can email to you. This was in our 1955 newspaper from Vegas...

and... The Simon Building...Geeez, never thought to look at the newspaper. (Then again, the last time I looked at this newspaper I ended up writing a 3-part article, based partially on what was in the paper! ) (and the fold & edges are pretty tattered, so we try not to handle it much)
