While employed at Oklahoma State University, one of the oddball responsibilities that I inherited was caricature illustration. It was a tradition that one of my library colleagues, David Thompson, would illustrate caricatures for retiring faculty and staff.
David was a professional caricature artist on the side, and when it was time for him to retire, many panicked, as there seemed to be no one around who could take on drawing his caricature let alone all future caricatures.
I stepped up to the challenge and began illustrating the retiree caricatures. I now accept caricature commissions both for digital and hand-inked physical illustration.
