These are 3.5" x 5-3/8" postcards with what look like photographs on the front. I found these in a box with some 1893 and early 1900's items. Two have Aug 1909 written on the back and one has Nov 1908 Taken at Harlem Park written on the back. As you can see they are very faded and worn. Some are badly stained. One has a tear on the lower edge.
