Nice and rare 1970s Acme Canada 30cm metric wooden rule made for Spectrum Educational Supplies Limited. Vintage made in Canada collectible marking and measuring tool and retro school ruler.
The Acme Ruler and Advertising Company, Ltd. has a long history in Canada. It was established in Toronto, Ontario prior to 1925 and made a variety of office and school supplies including rulers. It was located in the east end of Toronto. In the 1940s and 1950s it was located at 512 Rhodes Ave. It moved a short distance to 600 Victoria Park Ave in the early 1960s (between 1960 and 1963) where it stayed until 1972 when the factory moved to Mount Forest, Ontario. The company was eventually purchased by Acme United, an American company which started off as the Acme Shear Company (there were lots of companies named Acme back in the day).
Spectrum Educational Supplies Limited was founded in 1968 when the Toronto District School Board was searching for an educational supply company to provide them with custom elementary-grade science kits. They are still Canada’s educational products supplier.
