I recently came across a cache of old postcards while going through some of the photos and other memorabilia that I inherited from my late father (who, in turn, had inherited them from his parents—my grandparents).
Among these was a curious item that was titled a “Souvenir Folder of Austin”. It’s an accordion-folded collection of various sights (or sites?) around Austin. I can’t put a solid date on it, though there is a couple of good clues. First, the suggested postage is 1½¢, which corresponds to postage rates in 1938. Second, one of the postcards is of the Littlefield Fountain on the campus of the University of Texas. This fountain, by noted sculptor Pompeo Coppini, was completed in 1933, so this is from no-earlier than that date. Suffice to say, I’m comfortable saying that this dates from the very-late 1930s.
The postcards are credited to “Ellison”, which seems to be the Ellison Photo Company which, according to this site, was in business from 1900 through the 1980s. These are ostensibly photographs, but they’ve obviously been hand-colored and touched-up to the point that they look more like paintings or even hand-drawn architectural renderings.
