Gordy International.
The rack toys. Gordy of Yonkers, New York took the licence for the small stuff, the cards hung by the till rather than boxed on a shelf: two bubble guns, a flash gun, a sparkle gun, sunglasses, a hand painted pendant, a school slate, puffy stickers, a target set with a dart pistol and Panthro's nunchaku. 14 cards catalogued here across fifteen item numbers, with the Canadian releases through Charan Toy and the French ones through Masport.

Masport sold the property in France under its French name, so the same cards come back with the copy translated and the item number unchanged. Each one opens the item it belongs to.
About the line
LJN made the ThunderCats action figures. Gordy made the rack toys, the ones hung by the till at a dollar and change, and fifteen item numbers are confirmed so far. Everything came on a black card with the logo across the top, a caution line about small parts, character roundels wherever the blister left room, and the item number at the bottom right.
The Yonkers, New York address is on the guns and the pendant, but the play knife credits Henry Gordy International Inc. of Plainfield, New Jersey. Canada came through Charan Toy of Montreal and Toronto, whose cards run every line in French as well and carry a GY item prefix. France came through Masport, which sold the property as CosmoCats and translated the packaging with it.
