Check out these vintage pics from the Chicago Auto Show, which I hadn't seen before:

If I'm not mistaken, the '69 Burb cutaway is half Burb and half Pickup. In the second picture from the '73 show you can see that the next generation trucks also featured a half Burb/half Pickup cutaway (in the background). I imagine both of these were soon scrapped after the auto shows.
