You have some great pieces in great condition. Those would look great framed
I agree. But what are they worth? I've been looking for 6 years and haven't found another example of any of them, not even in institutional collections. There is one copy of the Sharmeter "sales king" ad on ebay right now, but it's a page cut from a magazine, smaller size than mine, so not really a comp, especially when mine has the sales letter on Sharpsville letterhead with it. As for the rest, nothing found, nowhere, nowhen. It's actually quite frustrating.
