Soaking Penny Blacks off an 1840s Wrapper: #philately 32

During my trip to the 2022 Stampex in London, I watched Bill Barrell remove Penny Black Stamps from an 1840s cover, this reveals an interesting lesson in the world of philatelic rarities and how they can deceive buyers. Also, using Hydrogen Peroxide, Bill removes years of sulfurization to reveal the true colors of the maltese crosses.
