RhysI have seen lots of this guys stuff and I think he (or a supplier)is making modern photos look older. I also think that the markings on the back of that Portland postcard are added after the fact and are not original postcard stamps. The lines and words are too grainy. Also, the left edge appears frayed as if it were a modern piece that has not been handled enough over the years to make the tiny paper shavings leftover from the the cutting process to be rubbed off. It also just does not look right. I have seen and owned thousands of real photo postcards from this era and I have never seen a RPPC with back stamps that look quite like that.
