The Charles M. Schulz Museum has obtained a few more originals from a proposed strip by Sparky that didn’t take off. They were even drawn on paper with pre-printed Peanuts panels. Click to enlarge to full size, and you can see that the original India ink is much darker than the printer’s ink.
The museum has assembled the originals, and some other material, for an interesting new exhibit. More information is available from The Washington Post.
The strips were supposedly drawn by Schulz, but I’m wondering if Jim Sasseville, his assistant for the comic book stories, had a hand in producing the samples. It seems likely to me that if “Hagemeyer” had been launched, Sasseville would have worked on it, just as he did for the “It’s Only a Game” strip.
