1935-36 Shirley's Gum Cards
Measure 1-9/16" x 2-13/16"
I couldn't find much in the way of information on these cards
other than the fact that they were issued in Holland, which makes sense since
I had acquired them from a vendor from South Africa. A few examples of
the front and back views of these Shirley's Gum cards are show below, followed
by a checklist of all of those that I have come across.
