I have in my collection "The Dutch Schultz Story" by Ted Addy. Apparently it was part of a series ("Public Enemies of the 1930's") published by Tower Books. Its a paperback that originally sold for 75¢ back in 1968 when it was first sold as a paperback.

Its an easy read and has 16 pages of pix. Let me know if you wanna borrow it, DC.

I just ordered a few of the ones you suggested above.
