Since February 21 is National Card Reading Day, here is a video of letterpress printing greeting cards in Pantone Green rubber base ink. This press run involved printing 30 cards using a 3x5 Kelsey Excelsior tabletop printing press. The photo engraving of the dog was made about 80-90 years ago. This card and other cards are available in our Museum Store! #CardReadingDay #SacHistoryMuseum #museum #printing #asmr #letterpress
