i love old cookbooks! especially the illustrations.
has anyone ever seen the "gallery of regrettable food"? it's all really hilarious illustrations from old cookbooks. i think most of them are from old editions of the women's day encyclopedia of cookery, if i remember correctly. the guy who made it has published the pictures and his comments in a book, so most of them aren't online, but there's a selection here: LILEKS (James) Gallery of Regrettable Food
his site is worth browsing around, there's some interesting stuff there.
