I am not entirely sure what a "Horse-Faced" tsuba is? Maybe AI has some catching up to do?
Title:
“Tokijima on a Horse-Faced Tsuba in the Month of April”
(馬面序政の月に時鳥)
Translation of the main text:
In April, the cuckoo bird is represented on this horse-faced tsuba (sword guard), appearing as though a cuckoo has been boldly incorporated into the design.
The maker was Masatsune, a master craftsman of the Kyōwa era in Edo.
Masatsune was originally a horse-gear artisan, but later began making sword fittings and produced many excellent works suited to the tastes of the time. He was especially skilled at carving horses.
As shown in this piece, the cuckoo appears vividly alive, as though it might suddenly fly away from the design.
This piece is made of iron. Its size is approximately 2 sun 7 bu (about 8 cm / 3.1 inches) in diameter, and the thickness is 1 bu 6 rin.
