What is the typeface used for the text "Molson Export" and "Molson Stock Ale"? I've found samples of it in use, at least as far back as 1964. There appears to be a full alphabet for it, as shown in these samples, and at least three different Molson beers during the 1960s-70s period all seem to use the same type: Molson Export, Molson Golden, Molson Stock Ale, and Molson Light.
Sort of reminds me of 'Lydian', 'Christiana', or 'Barbedor', though the former is not correct, and the latter two are not time period appropriate (nor exact matches). 'Castle', another newer font, also seems a bit similar, but again, too new.
The headline in the newspaper sample seems to suggest they actually set the type in that typeface, in order to print that newspaper ad. The newspaper type seems to be a different weight than the two label samples shown though.
