Does anyone know where I might be able to purchase the 4 books that Dan Mabey ha written about Post cereal cards? The 4 books are:

-"Cardboard, crunch, milk & scissors"
-"Bragging rights:the complete guide to 1962 Post cereal baseball cards"
-"Northern Exposure, the perils of collecting the 1962 Canadian post baseball card set"
-"Postage due,the comprehensive guide to the 1963 Post cereal baseball card set"
Any help would be appreciated.
