Once upon a time, Canadians would shop through something called a "Catalogue" which is sort of like a tablet, but with better battery life. Among the most popular catalogues in Canada was from a store called "Eatons", where you could buy anything from Hockey Sweaters, to even more Hockey Sweaters.
Check out these awesome scans and colour of Long Johns from the 1920-1921 Eatons catalogue! Courtesy of Michael S. From Saskatoon! Thanks so much Michael!
