I have found 19 so far of the 72
lightly hinged with gum in really good cond.
Edited: From the Jay Smith Link:
These labels were created and sold by stamp album publishers for the purpose of placement at the top of the first page of each country in a stamp album. In the U.S. we are most familiar with those produced by the Scott company and consist of Flags, Coats of Arms, and Rulers of the World; The first Scott adverstisement seen is in the 1902 Scott Catalog. A quick check also showed similar ads in the 1927 and 1950 catalog editions.
This type of label was often stuck into the albums of young collectors; they tended to tear them apart very roughly and then lick-and-stick them in the album. Examples with gum (even hinged) and in nice condition are very seldom offered! Spellings are as shown on the label.
Originally sold by the Scott stamp album publishing firm. There were surely must have been different editions of them over the years, but I do not have any information on how to differentiate and identify different editions. I am first aware of the labels being offered in a 1902 Scott Catalog. This group came from an album dated 1935 and which contained no stamps issued later than 1945. All are with full gum, hinged, and in excellent quality unless noted as SD (slightly damaged). Such nice examples are very seldom offered!
