What is the difference between the above souvenir sheets issued in 1933 and 1935. Scott
730, 731 and 766, 767. I have a set that is imperforate and ungummed . Don't know if they are 1933 0r 1935.
Both sets were issued imperf and without gum. The
are from the Farley special printings. You can tell if the sheets are from the Farley printings by measuring the gutter between the stamps. On
