From a 1979 Kenner in-package catalog:
"LUKE SKYWALKER'S Exciting LAND SPEEDER Vehicle!
The Land Speeder was among the first of the Star Wars vehicles designed for 3¾" figures. (Other 1978 releases were the X-Wing and TIE Fighter.) Due to its relative low cost, it was one of the first vehicles many of us had from the Star Wars line during the early years.
The Land Speeder was not offered as an ESB release but did make a return in 1983 in special "Star Wars Collector Series" packaging. Kenner brought back the Land Speeder, Darth Vader's TIE, and Dewback in essentially the same Star Wars boxes that they had originally appeared. The only difference was the addition of a "Collector Series" logo to the box.
