All U.S. currency printed prior to 1928 were known as "Horse blankets" or "Saddle blankets" due to their large size. Although similar in design to the dollar bills of today, the large size notes were almost one third larger than the smaller bills printed after 1928. The last of these large size notes was the prized One Dollar Blue Seal Silver Certificate of 1923, which features the portrait of George Washington painted by one of the nation's most famous artists, Gilbert Stuart. Introduced by an Act of Congress in 1878, Silver Certificates were backed by Silver held in the U.S. Treasury and could actually be redeemed for exactly $1 of Silver Bullion until June 24, 1968. The obligation is stated on the obverse of the Silver Certificate: "One Silver Dollar payable to the bearer on demand." The Large Silver Certificate is displayed on an acrylic frame and can be viewed on both sides. Comes with a certificate of authenticity.
