There is a “Gertie the Dinosaur” vibe to this story by Dick Briefer, from Frankenstein #5 (1946). I would not be surprised if that famous animated feature was a springboard for the Briefer story. “Gertie,” made by artist Winsor McCay (“Little Nemo in Slumberland”) had been popular in the early days of motion pictures. The first time I saw anything of “Gertie” was on the old Disneyland program of the 1950s, and I was fascinated by the stories of it being drawn frame by frame, over 10,000 drawings, to make the animation. To me, the definition of labor intensive.
You can see the McCay cartoon (featuring McCay and another well-known cartoonist of the era, George McManus, in a wrap-around to the animation) below.
