VERY FINE. THIS IS THE ONLY RECORDED COMPLETE SHEET OF TWELVE OF THE 3-CENT 1867 ESSAY WITH THE "VEINTE" SAFETY OVERPRINT, ATTRIBUTED TO THE ABRAM GIBSON PATENT.
The safety network overprint essays listed in Scott as 79-E26 are discussed in two important articles by James Lee, Richard Drews and Jan Hofmeyr in the 2016 and 2017 Chronicle (no. 251, pp. 260-274 and no. 253, pp. 64-72). Both Abram Gibson and Emanuel Harmon received patents for re-use prevention ideas based on overprinting intaglio engraved stamps with surface printed networks of light wavy lines in various colors. Either the intaglio ink or network ink would be fugitive and wiped away if an attempt was made to re-use the stamp. The essay offered here conforms to the Gibson patent and is so attributed in the second Chronicle article. This is the unique full sheet of 12 and serves as strong evidence that all the safety network essays were printed from miniature sheets of 12.
