The Columbian press is a type of hand-operated printing press invented in the United States by George Clymer, around 1813. Made from cast iron, it was a very successful design and many thousands were made by him and by others during the 19th century. Columbians continued to be made as late as the early-20th century, 90 years after their introduction. Despite their age, many are still used for printing, especially by artists who make prints using traditional methods.
The Columbian design is also notable for its elaborate, symbolic ornamentation.
