Constitution and World's Fair Issues
With the celebration of the United States Constitution Sesquicentennial from 1937 to 1939, the holding of the New York World's fair and the Golden Gate International Exposition in 1939, many nations saw fit to issue stamps to note the event and the good-will existing between them and the United States. The Sun has compiled all available information about these stamps and presents it for the first time in booklet form. (text from the inside cover of the booklet)
The booklet has three sections; The first is a listing of the stamps, the second is a description for each country and information about the stamps. The remainder of the booklet is for advertising.
For those interested in the stamps here is a link to a PDF file containing the entire listing for Constitution Issues, World's Fair Stamps, and Golden Gate Exposition Stamps.
