Here is a scan of the Portola Revalued 4 cent Lincoln Postal Card (Scotts UY 18 [reply portion]). The 2nd image is that of the regular card (UX-48 without the uprating cancel).
This card was approved by the USPS, but since it was NOT overprinted by the USPS printing office, Scott's and other no longer list the item in their catalog(they did for several years however).
This card is considered "rare" by most postal stationery collectors.
I was fortunate to pick it up in the early 2000's to add to my collection.
I thought that some of you may have never seen one of these, so I would share.
