Yikes, that was what I was going to post, after I finish reading the thread--but you made me do it now. Could not believe it was the very first thing listed! Has been my cooking bible for at least 30+ years - and my parents for many years before that (since however long it has been in print).
And it has that wonderful recipe for "Preserved Children" - I loved that as kid. Mine is, alas, in storage - see the lead article and every post on this thread as to "why". But I have to see if I can find it online.
Another funky little item worth shelf space is a cookbook from ~1953 called "Hummingbirds and Radishes", very gourmet for its day. I use it frequently.
