If somebody sends me a PM to remind me, I can post a photo of the DVC Member sticker that's on our new van. For some odd reason, I purchased two of them back in 1998. We recently sold the old van and my wife was worried that she would not be able to recognize our minivan without the sticker in the rear window. Fortunately, I was able to find my "spare" sticker. Problem solved.
The sticker was inexpensive and it survived 5 years in NE Ohio weather and still looked none the worse for the wear. I didn't see any of these stickers when we were at WDW last month. I didn't realize that it was a collector's item.
