By popular demand (from Mike Lynch), here are profiles of the five other instructors on the staff of "The Professional School of Cartooning". For further details, see my posting in "Eli's Corner" dated January 2, 2008, about the four cartooning Roth brothers. I wish I could give you updates on all these cartoonists, but I have very little info to impart. All of them were prolific and popular gag cartoonists in 1947. Of course, Lawrence Lariar (apparently the founder and "Executive Director" of this correspondence school) was also a Cartoon Editor for several major publications, and also an anthologist of a great many cartoon book collections.
Wow, Adolph Schus was selling cartoons in 1926 — now, that makes me feel young!
