Nintendo Greeting Card
Nextoft Corporation (1989)
I found a pack of greeting cards at the Hometown Farmers Market from 1989 that were made using artwork from Super Mario Bros 2. I always thought that the mushroom was just part of Toad's head, but it turns out that it was a cap all along.
The cards were produced by the Nexoft Corporation, who published several NES and Famicom games when these cards were on store shelves, including Castlequest, Wizardry, and Faria. In 1991, the company changed their name to the ASCII Corporation. They continued to publish games under that name for the rest of the decade and into the 2000's until they merged with MediaWorks in 2008.
