1/2 Quetzal 1955/56

Waterlow & Sons had been printing Guatemalan banknotes since at least the 1920s, and by the mid-1950s the relationship was well established — though the firm itself was in its final decade, absorbed by De La Rue in 1961. The half-quetzal denomination survived into this period largely because the quetzal had maintained its one-to-one parity with the US dollar since 1925, a monetary anchor that actually made fractional denominations more useful in daily commerce than they would otherwise have been.

Pick 29 is the last series to carry Waterlow's name on Guatemalan notes before the printing contract changed hands.
