So, is this the brother of the soda jerk at Woolworths? It's certainly NOT Eddie Fisher, though people these days wouldn't know that. You have to be of a certain age to know Eddie Fisher and young people today would assume Eddie was a bowler who had a weekly show and drank Coke in table cloth shirts.

I'd say this is by the same illustrator as yesterday's and again I have no clue who it was. I'd say they worked from photos which means somewhere out there are people who posed for these illustrations or perhaps their relatives who cherish these images.
This is on the back cover of the April 1954 National Geographic. National Geographic is a gold mine, I tell you. A GOLD MINE!
Unfortunately the next year, 1955, the Coke ads are photographs, no illustration, though I haven't yet found the December issue.
