1893 London Philatelist with "Tilleard" Die Proofs (11 different on 3 pages) and Plate Proofs (190 in total on 4 pages). The retail value of these is approximately $7,000-$8,500. This is one of the few (and perhaps the last) remaining intact bound volume in private hands. In addition the articles and the ads make for great reading. Estimate $4000
