Vintage Huntsville Map 1971

The image shows a vintage topographical map of the Huntsville and Algonquin Provincial Park area in Ontario, Canada. It appears to be part of a series of maps, possibly a "Half-Inch" scale series, which were popular for touring and navigation. 
The map covers the region around Huntsville, Ontario, and a significant portion of Algonquin Provincial Park in Canada. 

The "Half-Inch" designation in similar map series refers to a scale where half an inch on the map represents one English mile. 

While not explicitly stated on the visible part of this map, similar vintage maps of this type were often published by well-known cartography firms like Bartholomew, known for their detailed and regularly updated maps. 

These types of maps were commonly used for activities like touring, cycling, and general navigation due to their clarity and accuracy for the time.  Smoke free home
