In the 1960s I was marking up copy as a type specifier in an advertising typography house in LA when they closed shop. One of the items I was able to take with me was a 1923 ATF specimen book that I'm now offering for sale on ebay:
It has been well used and shows some signs of wear, but it is in excellent condition considering its age.
This is an invaluable reference volume for any serious digital age designer.
I've placed quite a few images of various pages of the book on my ebay listing, but if you have any questions, feel free to ask.
