A strange pattern but it's just a double fan.
Two fans in each block
The small red curved piece is what catches your eye.
It's in BlockBase as #3353, but the published names Gypsy Trail and Snake in the Hollow come from 1970s publications. It must have been published earlier in the 1940-1970 years. These three quilts look to be from that date.
UPDATE: OR do they? After thinking about this I think they must all come from the Quilters Newsletter pattern Snake in the Hollow in 1978.
From the Quilt Index
This one's in the collection of the Museum at Michigan State University. I
think it was once in Merry Silber's collection. The dealer said it was found
in an Indiana attic.
I made a QuickQuilt in BlockBase of #3353.
And that's the only one I am going to make---
A lotta curved seams.
