Here is a very nice and seldom seen Sharples Separator advertising pinback button to add to your collection. This was recently acquired and is being offered here for the first time. Sharples did a series of these advertising pinbacks, and this is one of the more rare ones. It is excellent condition retaining its original back paper insert from the Whitehead & Hoag Co. Newark, N.J. This insert dates this pinback to c. 1898-1900. It measures 1-/14" across. Don't miss out on adding this great piece of American Exposition history to your collection. Our photos should tell you just about all of the rest. Please email us with any questions or concerns that you may have. You will be answered in a timely manner. If asking on or near the weekend, give us a little more time to respond, as we may be away on business. Also just to note, our shipping charges include insurance. We have had too many problems with the U.S. Postal service. We insure every package to protect both the buyer as well as us.
