Can someone enhance these photos?

Hi everyone, recently my grandfather gave me this piece of printer paper with these 4 photos on it to be scanned and sent back to them. For context, this car was the last drag car my great-uncle built and drove, and now these are the last pictures my grandpa has of it, but also that time. I was wondering if they could be enhanced a bit, and maybe the blue lines from the printer be smoothed out/removed? Any help would be appreciated, as I'm hopeless with picture editing, thank you!
