An Unusual Postage Stamp
What’s a Z Grill? Is it the latest Infomercial gadget promising to remove all the fat, retain all the flavor, and reduce all the guilt associated with preparing your favorite but normally forbidden foods?
Is it the technique which Zorro used to interrogate the bad guys before dispatching them with the three trademark swipes of his sword?
No, the Z Grill is neither of those, and you could probably keep guessing for a long time, before you got it right. The Z Grill in question is, of all things, a rather unassuming blue-and-white 1868 one-cent postage stamp, bearing the profile of the first US Postmaster general, Benjamin Franklin. What, besides its age, makes it anything but an old stamp?
