Portrait of Alex Katz the painter
http://www.brendazlamany.com/bald/portrait-23.html
Thanks Luvlyness :) The closest I could find of a picture of the painter/artist, Alex Katz was this:
http://www.keithwidyolar.com/shoots/20050809_Visionaire_AlexKatz/
It claims to have been shot on August 9, 2005, the same year of the photos taken at the Freaky Tiki. Hope it helps.
I honestly can't tell. It's close for sure, though! You may be onto something there. I'll keep digging. By the way, I got the above pic by going to www.altavista.com and doing a search on Alex Katz and clicking on images to search.
That looks like the same guy in the photo with Anna! So they may have used the name of a guy they knew for the scripts.
