This is another photo of Frankenstein actor Glenn Strange reading some comics, this time the Sunday Funnies.
The photo comes from It's Alive, film historian Greg Mank's superb book on the Frankenstein movies(sadly and criminally oop). According to Mank, that earlier photo that has been widely reproduced wasn't just a publicity or gag photo--Strange really loved comics, read them all the time, and this second photo backs that up.
Wow, he was Frankenstein, a cowboy, and loved to read comics. Glenn Strange sounded like a fun guy, didn't he?
