Pro wrestling would sometimes turn up at unusual spots. Drive-ins, stores, camps etc
This one from 1978 has Phil 'Whipper Jr.' Watson and his crew of trainees appearing at a car dealership in Richmond Hill, ON. Phil had put on shows in the early 1970's around the small towns, sometimes in partnership with Dave McKigney. This one came at a pivotal point for the smaller guys like McKigney as the Tunney's (Jack mostly) had started to oppose the circuit in Ontario.
Jr. may have been trying to drum up interest or test the market before putting on some shows.
The Ad itself is similar to ones used by the Maich brothers in Brantford and area in the 1950's and the dealership or where it once stood - is now a condo development.
