No, these are scans of the full pages from the comics. I did have to do a lot of cleaning up in photoshop.
By old papers, do you mean the John Carter newspaper strip?
Sorry just dug them out. No John Carter. Mainly Disney, Flash Gordon, Jungle Jim, the Phantom, Prince Valiant. These would take a HUGE scanner to get them in one shot! Mine are newspaper strips, I thought at first thats where yours were scanned from!
Nope these are from the Funnies comic book series and predate the JC newspaper strip by a couple of years. John Coleman Burroughs also did the newspaper strip but it was only in a handful of papers and pages are tough to find.
