The August 1927 issue of the En-Ar-Co Booster , the publication for Canadian Oil
Companies Ltd. dealers, announced a new contest .  Dealers were invited to send in a short
letter ,telling what the Boy and Slate is doing to increase their sales of En-ar-co Motor Oil
and greases and include a snapshot of the Boy and Slate in front of their place of business .
The fifteen best submissions would be awarded one of 15 gold-filled watch charms that
are presented as this months feature .
   En-ar-co Boosters usually carried one or two pages of stories and photos from dealers
across Canada .While I have found no other evidence that this contest was repeated in later months , I feel that the offer may have been extended to promote dealer participation.
   There may, or may not, have been more than these fifteen awarded.
