From the late 19th century a homespun feather mattress tick cover in a red, white and blue check ~ great Americana colors! Very suitable for a country primitive farmhouse decor. My opinion, a factory made homespun fabric, home sewn on a treadle machine.
The tick is sewn with three width of fabric, each width is 32" wide. Overall size of the tick is 64" wide x 48" long, Opening on one end, with the opening length 50". No closures, such as buttons etc. Possibly a linen fabric or a blend of linen and cotton. Durable weight.
Condition is very nice. Perhaps never used.
