The Jan/Feb 2007 "special issue" of American Photo magazine has a quick article on p 124 about Jeffrey Aaronson's project consisting of portraits of Craigslist "personals" advertiser, made using a 20x24 camera that's show in the accompanying photo. Man, that thing is HUGE. Anyway, I haven't read the article but it said something about polaroids - does polaroid make 20x24in film?
