I have a considerable number of used American stamps, and I think this stock book is quite good. The American stamps seem to have been carefully sorted, perhaps by state, at the beginning. It has 12 sheets with 24 pages, and each page has 10 rows. It's made of glassine paper. The approximate size is 27cm high and just under 21cm wide. The condition is generally good inside, but the cover and sides of the stock book have some discoloration and changes due to aging. Please understand all the details. Thank you very much. m(_ _)m
