I've mentioned USPS Commemorative Panels in other threads as one of the best ways to acquire engraved vignettes of the American Bank Note Co. Here's a couple great examples of why I like them so much. The first two years of the series, 1972 and '73, ABNC chose to illustrate the annual Christmas stamp panels with four of their best known engravings of Santa. These are rarely seen on banknotes and other securities, and in fact I think most were engraved by predecessor companies before ABNC was formed in 1858.
Enjoy -- and Merry Christmas to All!
