Above is an image of one of the rarest Sliders merchandise items. In 1995, the Pilot episode was officially released on video...but only in Australia. Even more than that, the video was only ever sold at rental price (around $100 per copy). These factors made this video extremely rare to begin with...and the copies out there were practically all bought as previously viewed (or else conveniently "lost" before they were returned ;-).
Thankfully, we can at least see what the packaging looked like, thanks to Noodling.
