Today I picked up a photo album containing several space shuttle photos and photos of what I am assuming are some of the astronauts. The space shuttle photos are 8 X 10 and the astronaut photos are 3-1/2 X 4-1/2. The space shuttle photos have some kind of marking (looks like a cross hair) about every 2-3/4" apart. The astronaut photos don't have these markings. Could these be original NASA photos? If so, any value? Does anybody have any idea what the cross hair markings are?
I've scanned a couple of each, there are several more.
