A wonderful collection of 19th Century (1860s-1890s) including Back of the Book Used in stock sheet. A very nice addition to any 19th Century collection. Have actively collected stamps and related philatelic materials since 1977. I fondly remember going with my uncle in the 1970s to the Rexall Drugstore where the Postmaster would show me many current and older issues in the little Post Office (the “Stamp Cage”) adjacent to the pharmacy counter while my uncle talked with his friend the pharmacist. I cherish those memories. I have added a fine selection of many stamps, covers and philatelic materials to my store.
