The Tachi bina is an older form of Japanese Hina dolls from the early Edo period(1603-1827). The earlier Tachi bina were not made to stand up, instead they were made to lay down or lean on the display. The faces of this set appear to be old with a beautiful sparkle on white gofun crashed/ground oyster shell), probably from late Edo period. We are not sure if the clothing was redone later or not, the silk brocade has paper backing (with washi hand made Japanese paper). The hair on dolls is real but brittle from age. One side of hair of empress doll is detached. This can be shaped (to some extent) if the dolls are to displayed standing up. For her hair sake, It may be better to place them on cloth backed board and hang it - most of standing hina doll from this period, particularly female dolls, had lost their hair by now. By placing the dolls on the board, instead of standing them up, you may save the hair of the empress. The emperor is 12 1/2 inches, the empress, 9 3/4 inches tall.
