Here is a Crams Hard Surface Road Map for the state of ILLINOIS.
The map appeared in a 1928 Calendar.
This map is in 2 colors - dark blue with red highlighting/outlining and measures approximately 12" wide and 15" tall. The map is in good condition. There are a few small nicks and tears around the edges that should be easily covered with matting if you are framing. There is also a fold across the middle - this is how the map was stored for years; map will be shipped to you folded in this way. The paper has some tanning.
Legend indicates the following road surfaces
1 Concrete & Brick
2 Gravel, Stone, graded
3 Good in Dry Season Only
Shipping is by USPS First Class or Priority Mail in cardboard protected envelope.
