Here's an interesting item I first picked up from a post on VSC ... but sure enough, the USPS Facebook images still lists it -- a $1.02 stamp that was apparently in the planning stages but was never issued in 2011:

Since it was posted by the USPS on Facebook, and the rate is now meaningless, I suspect it was planned in anticipation of the first postage rate hike announced early in 2011 but later denied by the Postal Rate Commission and the stamp design was never taken down from the USPS Facebook site.
Not that the stamp is all that attractive, but it does seem rather odd that if the USPS had selected a stamp and its designer all picked out, that they wouldn't have just adjusted the denomination and issued the stamp already in the planning stages for the 2012 rate increase, but since they just announced the $1.05 Lancaster County, PA stamp for that purpose, it seems that this design has fallen by the wayside.
It makes you wonder just how many stamps get this far into the planning stages and get pulled for one reason or another.
