In 1975, Jack Harkema sketched these caricatures of Upjohn employees. Ron Stryd worked in Drug Metabolism Research and gave this to me in 2025. He's the one with an animal rear end getting an injection. Apparently this was because Ron worked a lot with with the Animal Health part of the company. I've included close-ups of all the caricatures. Alas, Jack Harkema died in 2006. Here's his obituary. This is a delightful piece of Upjohn folk art!
