This is a stick-on applique patch of Superman from a company named Wrights and is in the original package: shrink-wrapped on a card. The package is not dated, but judging from the typography and the package design, I think it’s from the 1970s. Superman stands about 3-1/4″ tall.
Wrights released larger 4-1/2″ high versions of these patches, too. Hake’s Americana recently offered a complete set of loose Justice League patches, linked so you can see the rest of the series.
Though I’m not sure this is particularly valuable, these aren’t easy to find in the original package.
