"Iconic"! Along with the TIE Fighter, The X-Wing has to be the most recognizable vehicle ever created for the Star Wars universe. Like many young Star Wars fans, I had one as a kid. Not surprising since the X-Wing was one of the three vehicles released in the first wave of 1978 (the others were the TIE Fighter and Landspeeder).
Although I still have my own childhood X-Wing (seen in the photos below) the Canadian Kenner box it came in is long gone (drat!), since replaced with a Kenner US box obtained from an eBay seller.
The box is rather beaten up but I still like it - the "LP" (Long-Play) logo on the box front denotes a "first-wave" (1978) release - as with other Kenner US releases, the later box versions dispensed with the logo. Of course, once the "Luke Skywalker X-Wing Pilot" was released in the second wave of 21 mini-action figures, the box photo was updated to show that figure in the cockpit rather than the Luke "farmboy".
Here's my original from 1978. Yellowed canopy (this is common) and dead electronics, but otherwise in good shape and fully functioning. The wing-opening mechanism even works and holds the wings open, which is another item that's prone to fatigue and failure with age and use.
Close-up of the "controls" - from top to bottom: press on Artoo's head to open the wings; slide the switch to close the wings; press the button to activate light and sound feature.
"Kenner Products" copyright info on bottom of fuselage. The ship has been re-released in both PotF2 and "OTC" (Original Trilogy Collection) versions, with some different paint deco and deletion of the light and sound features. At the risk of sounding like a broken record, "original is best!"
