The Grand Canyon blanket was introduced on November 1, 1926. 
Felt bound top and bottom, it was available in six body colors -- 
straw, drab, white, brown, rose and delft blue -- having seven sedimentary stripes 
at each end and, until 1938, four points in the lower right corner of the center field.

 
 

The Grand Canyon blanket used Southwestern colors evocative of the 
Craftsman era.  The straw blanket is pictured above and the rose and drab
blankets are shown below left and right.  A strong seller, the Grand Canyon 
was one of three National Park blankets offered throughout the 1930s, 
the other two being the Glacier Park and the Yellowstone Park. 

       

After World War II, the Grand Canyon was available in a variety of plaid patterns
more typically associated with "stadium blankets" taken to football games.

 

    

Dropped in 1973, the GrandCanyon returned in 1978 and continued in
production until 1992. It was reintroduced in the mid 1990s with new 
blue and gold colors (shown below), and remains in the line up today.

The above current Grand Canyon National Park blanket should
not be confused with the Grand Canyon Blanket (below) that was
commissioned
by the Dewey Trading Company in the 1990s 
from artist Ed Mell
 as part of its Signature Collection.
