FELT PENNANTS
Pennant cards are what are called generic postcards. They are mass produced by the millions and then are either stamped with the town or city name or, like these, pasted with felt triangles. I don't know why there was such a fascination with Dutch children and humor, but obviously there was. As you can see from the first three cards they varied the pennant colors, and if you look closely you will see that on the first 21 cards Cincinnati is spelled incorrectly. They apparently made a immense number of these and then decided to use them anyway or they would have lost money on the Cincinnati part of their venture.
