The United States Postal Service is getting ready to issue a new stamp in celebration of the upcoming solar eclipse. I have received my first inquiry from a collector wondering if there will be any preservation concerns with this new type of stamp. I have contacted USPS and the Thermochromic component is in the ink only. Wikipedia offered an overview and obviously the material has been around for decades and we have all used many items with this component. I am wondering if any out there has had the opportunity to work on objects with this element or have objects with this in their collections, especially paper based material.
Once the stamp is issued I am sure there will be a few more inquires coming our way. I will give the usual information but just want to be sure there is not something I should be looking out for since we will be adding them to our collection as well. Just trying to do my due diligence Enjoy the solar eclipse if you are lucky enough to be in its path!
