Mint NH examples of the 1936 issue 50pf dark blue and 75pf dull green "Hindenburg" airmails, in corner blocks of four and singles. The gum is unblemished and undisturbed, which is scarce but "bad news" because the gum contains a good amount of sulfuric acid which eventually destroys the paper. These are already beginning to show signs of acidification and there is some minor perf separation. Washing off the gum will neutralize the problem. 2019 Scott for Mint no Gum $195.00=
