Gloria Sweethearts Print

Donald Art Print Co., Inc. print in frames by Lambert Products. It measures 5 x 7 inches. It is dated 1957. The only information I've found about the artist are works in a few older children's books. The The frame is a very lightweight wood. The frames show some wear, but the print has no damage, although there is a general aging of the paper. There is a reflection of the camera, which might appear as damage. I have an additional 2 prints of the same series (same size and frame) available and priced individually. I need your zip code to calculate the postage.
