Super rare Sunrise in a Cherry Blossom 'Hinode Sakura' maker's mark.
This is the only known example of this mark with a double seal, where the 'Cherry Blossom' is stamped on the outside of the second seal and the 'Sunrise' is stamped on the inside of the first seal.
This float is also the only known example of this mark on a 10 inch float. All other known specimens of this mark are on 4 inch floats and there are only 3 of them.
Truly a one-of-a-kind float!!!
