Issued during World War II as an emergency issue after the attack on Pearl Harbor, the Hawaii Brown Seal Note was a response to a possible Japanese invasion. The $1.00 United States issued currency has the word Hawaii stamped on both the right and left sides of the face of the bill. A large outline of the word Hawaii dominates the reverse of the bill. The silver $1.00 certificate is also recognizable by the brown treasury stamp and serial numbers that adorn the bill. The Hawaii Brown Seal Note is mounted in an acrylic 9 1/2 inch by 11 1/2 inch frame and may be viewed from both the front and back sides. A Certificate of Authenticity is stamped on the matting.
