value of old pictures as documentation

[black69]

I was going through a ton of color pictures I have for a 61 vette I have that I am going to sell. How do you gauge the value of pictures toward authentication of a car? I have protecto plate on my 69 camaro, I have the IBM card from chrysler for a 67 hemi car I have. But on the vette I have, all I have are old registrations back to 67, the old original california black plates, and the color pictures the original owner took. Some pictues are with a baby seat in the middle of the 2 seats which is really cool (yes I know that won't add value, just humor). Do pictues really add any real value on authentication when it comes down to a sale? Its a fuelie and the fuelie script on the fenders shows up in the pictures. But is that good enough for someone if there is no protecto plate or window sticker? Any opinions welcome.
