Original space memorabilia, including original photos, are very popularly collected. Original NASA photos will typically have their stamping on back. I can't tell you if your photos are original just from these images, but they do have color fading/discolorization consistent with old color photos.
If you can see the backs, they may have the photopaper manufacturer branding (Kodak, etc) that would date the photos.
