The Banco de Guatemala series printed by Oberthur in Rennes ran through the 1990s as the bank consolidated printing contracts away from British suppliers it had used in earlier decades. Oberthur's intaglio work on this denomination is competent but unremarkable by the firm's standards — the real engineering interest lies in the embedded security thread, which Guatemala adopted relatively early among Central American issuers as counterfeiting pressure on the quetzal increased through the late 1980s.
Pick 81 was eventually superseded by polymer issues as the region moved away from cotton substrates entirely.
