Is it possible the quilt comes from the book Bed and Breakfast Quilts by Mimi Dietrich and the person who quilted Vintage Memories in the picture is Othie Lingle? The design looks like it could be Mimi's. Or, did Othie Lingle create the design and Mimi features it in her book? Book is out of print. Not much info given with online references, as the links are older.
There are references online to email Othie, and no doubt Mimi would be glad to hear from us as well.
