JP - you were the inspiration for my seeking out the documents. Really enjoy that car show photo; I see at least a 220a, a 220S, a 300, and an Adenauer. Looks like Cooke was really into M-B; the background sign says First Canadian Showing, and my 1953 invoice doesn't list Mercedes as a marque they carried at the time. I'm guessing the photo is from 1954.
By the way, you say "What's the address". What address do you mean?
Thanks.
Tom M.
PS - have to chuckle - that sign also shows Daimler Benz engines from 10hp to 2500hp.
