Dave Jenner (Punch and Jimmy artist from The Beano of the 60's) started the strip..
So that is how Sammy got his name...he shrank!!!
Here's the "origin" of Sammy Shrink from Wham! 118.
As Terry Bave explains in his autobiography 'A Line in Chuckles' Sammy Shrink was his first professional comic strip assignment. The editor of Wham! told him it was the least popular strip and on the verge of cancelation when he took it over with no.151 - yet it went on to be his longest-running character. To begin with he was asked to ghost the original artist in order to maintain continuity, but over time he was allowed to inject more and more of his own style.
Terry Bave's first official Sammy Shrink.
Here's Terry's first published Sammy Shrink strip, as reproduced in the first section of his autobiography when it appeared in the Winter 1985 issue of Golden Fun. Strictly speaking it wasn't his first attempt, however, as he was so dissatisfied with how that turned out he tore it up and started again.
