Are these photo's valuable? Thinking about purchasing...

They are old Kodak's from the 70s-80s.

I've seen these pictures all over the internet, BUT are they worth anything because they're old?

Lot of 3 Candid Family Photographs Pictures Elvis Priscilla & Lisa Marie Presley

US $19.95

Ask and confirm if they're originals... when printed?

I doubt they were printed in '71.

US $19.95 for 3 Reproductions? No.

I've seen these pics posted here but can't find them.

This shot is my favorite...
