Just last week, I found this quilt and realized I'd had it for a couple years but never really photographed it. So, I got a picture, and today received some information that helped identify the quilt. Connie Chunn, who presented a study center about the Ladies Art Company at the 2010 American Quilt Study Group Seminar, sent me a copy of LAC No. 488, the "Suspension Bridge" pattern.
Looks like a fairly close match, even though the quilt in the diagram has a slightly different configuration. The original design called for an 18" block. My quilt has a 15" block. However, it is the same number of points and same block design.
The pattern was published in 1922, well before this quilt was made in the 1930s. There were several variants with similar designs, such as Broken Circle (Clara Stone), Sunflower (KC Star), and Sunburst (Lithgow). The block can be found in Barbara Brackman's Encyclopedia of Pieced Quilt Patterns, #2663.
