Question - 1961 Wrigley Field Exhibits

[quinnsryche]

Hi, if they are blank backed, are they reprints? I have stack of them and most have the postcard printing on the back but 2 are completely blank. These 2 look lighter in color than the others also. Does anyone know for sure if they are real/reprints? Attached are some photos for comparison sake.
Thanks in advance,
Tony

They look real to me. These come in both PC and blank backs.

They come both ways. As for image, some of the cards have crappy source photos.

Thanks for the info guys. The photos are not the greatest, look at Bresnahan, he looks like he's in a cloud of smoke!
