Vintage 70s Cardigan with Early 1900s Upcycled Quilt Patchwork

An adorable cardigan sweater in blue wool, it is collarless and has decorative buttons in heart shape, at the opening. The front and back are decorated with a patchwork design that rescued parts from an Edwardian era quilt. The front strips with butons and holes is probably the same age!
Lined at the interior. No pockets.
Interior features the most charming detail with the following statement written in black marker: Stolen from Laura Staebler

Homemade, it fits like a ladies medium

Shoulders 16"
Sleeves 23"
Chest 38"
Waist 34"
Length 21

Condition: good with some of the light patchwork squares showing some discoloration as seen in photos. This is to be expected as they likely reused parts form an antique quilt. Freshly laundered, no holes!
