I collect and enjoy them, particularly those from 'Bloom Bros Co' as shown and/or those which actually got sent through the postal system. They typically contain 20 individual cards and are 3" x 2". If anyone have any they would like to sell of trade, please let me know. Don
I don't have anything for trade, but, just for the sake of keeping on topic, I found a set some years ago from Camp Petawawa in the province of Ontario with military scenes. Items like these also let me know what to look for in regular sized postcards as well. Usually, about 90% of the time anyway, the images you see on the miniature ones can be found on larger sized ones as well for most given topics.
