rare vintage Summer Flowers French glass jars w/ seals, never used kitchen canisters set

Vintage French canning jar style canisters with wire closures and hinged lids, and original hermetic air tight seals. This set was never used, I opened the box to get you these photos. The box is worn, the jars are in excellent condition.

Pattern is Summer Flower, with multicolored floral print (poppies!) on clear glass. It's a set of four canisters in graduated sizes. Largest is 9 1/2" tall.
