I agree with your rationale that it is unusual if they were all printed at the same time that they would have different backs that does not make sense. I suppose it’s possible the photos were sold and then whoever bought them printed the back on there but if this were the case you might think there would be blank backs out there. Are there?? Otherwise it seems plausible they were printed a few different times possibly different years.
