RPPC's--Looking for some expertise--

[dougscats]

Thanks for the replies thus far.
Jim, the ones I have, the photos themselves do look consistent with yours, though mine have a name printed on them.

I can still return these,
but I'd just as soon keep them if they're real.

I've looked at them under a pocket microscope, and they are real photos, not prints.

For those of you interested in real photos, Here are links I found on Google:

Any other expertise about RPPC's in general, or in particular as to whether or not these are real, would be appreciated.

Let me add that there are two lines erased under the Photo Postcard stamp.
The first line says: S ... [Sports?] Cards B ? Collectors
The second line ends in a number--[I can discern ... 62 on three of them]--could be a zip code at the end of an address.

Here are the other two cards:
