Such a cute couple! Regional Jewish cookbooks, eh? That's an interesting topic for a collection. My mother-in-law probably has the world's largest collection of Lutheran church basement lady cookbooks. I've looked at some of them, but they all seem to have the same 120 recipes.
Not that there's anything wrong with that, of course. They DO all have different covers, anyhow.
I have at least that many books, except many of my shelves are two deep. Most are rescues from garage sales. I hate to see a good book thrown away.
