Not to be confused with the "Rear
Bumper" television show that Shep did in Cincinnati, these were a
series of short films done by Shep for PBS to fill time at the end
of the broadcast day in 1969.
"Shep did a series of rear bumpers in 1969. These
were aired
nightly for a month at the end of the programming day. They had no
time
requirements because they could run as short or as long as they
wished."
