Vintage 1950s KEM Plastic Patch Spackling Compound Box with Powder

For your consideration is this vintage box and contents of Kem® Plastic Patch Spackling Compound manufactured by The Sherwin Williams Company. I believe this to have been produced during the 1950s or 1960s, but unable to validate the dates. The box has a 2.5 pound capacity, but there are only 1.3 pounds of spackling compound / paper within the box. I have bagged up the powder so not to make a huge mess in transit. The box is in pretty good condition with slight shelf wear, most notibly on the top. It measures approximately 4 inches long x 3.25 inches wide x 5.5 inches tall.
