Johnson's Nebraska, Dakota, Colorado & Kansas.
This famous map was published only in 1862 before the creation of Wyoming and Montana. "Greater Nebraska" has been reduced by the creation of a huge Dakota that extends from Minnesota to the Continental Divide, across most of today’s Montana and much of Wyoming. Nebraska now has a long panhandle that extends to the divide and is squared off with part of Utah giving it an elongated appearance. A very nice brightly colored map
Condition is very good. Image size is 12.5 x 15.5 (inches).
