Two Stockbooks with Mint and Used Collector's Duplicates, 1858-1973, with regular issues ranging from #s 3/872, mostly in complete sets, with most of the value in the first pages (for example, the two first pages catalogue about $1,600), followed by early airmails (to 1944), then postage dues, officials, parcel post, newspaper stamps and special delivery. A second stockbook is devoted to airmails only, ranging from 1944 to 1973. Not much duplication noted, except for a few that have a mint and a used, and there is a mix of mint and used, including never hinged. Overall fine to very fine, see scans for a small sample.
