1907 Tigers reprint postcards, set of 15

[billyb]

I was going through some of my boxes with the cob webs on them, and found 2 identical sets of the 1907 Detroit Tigers reprint postcards. Each set of 15, was originally published by AC Dietsche in 1907.
I obtained the sets around the mid 1980s. I believe they were reprinted by the Detroit Baseball club, but not sure as there is no information on the small envelope they came in.
The photos on the postcards are very good copies. They measure 5 1/2 x 3 3/8 inches.
If anyone has any further information on this set, please let me know, or what would be really cool is to see if anyone has any of the original photos of these pictures on the postcards.
What concerns me a little, while trying to research these postcards, I noticed in 2011, at the REA auction, it appears a set like these sold for big money, over 2K, and was represented as original postcards????
These postcards clearly have reprint on the back, but I did not see that on the ones sold at the REA auction. This is why I posted this reprint set on this forum. I will attach 4 of the set.
