The Land Speeder was the least popular of the Series 1 ships and apparently not released on Empire Strikes Back packaging like the TIE Fighter and X-Wing. Its scale was larger than that of the other Series 1 ships but was still too small to fit in the with 3 and 3/4" line of toys.
It also was distinctly lacking in action features - 'wheels give 'Floating' ride' was its selling point. In its favour the suspension was pretty solid!
The observant amongst you may have spotted that Luke is in the driving seat, whereas the screen footage of the hunt for R2 has C3PO driving. On the cardfront Luke appears to still be a passenger with Ben now at the wheel. However, the photo has been flipped and Luke is now in control of a left hand drive speeder!
The lower of the smaller photos on the front of the SW12A was also flipped and does have C3PO in the drivers seat. This mirror image was a mistake on the first release of the cardback, and subsequently corrected for the SW12B and all the non-US releases.
