The library is one of the most popular locations portrayed in postcards. Many publishers and editions exist and some even use the same base image for their hand coloring. This can lead to a “Wheres Waldo” kind of puzzle in determining if two cards are the same. The first THREE cards below are of the same base image but hand colored by different artists. The difference in the clouds is what I base that on. I particularly like the fourth image where the artist has taken the liberty of placing the building on what appears to be a ridge with a scenic vista. Many postcard images on this site look like I posted duplicates, but either subtle differences exist in the image or the publication details on the back side tell me they were separate editions.
