This relatively uncommon, large cover(quite clean, but with tears of the top layer of the envelope's paper(either side); intact back flap, but with a tear at the top, left side, connected to the original, rough opening of the envelope) was sent from Shintake(a.k.a. Hsinchu in Chinese), Taiwan(then occupied by the Japanese), to Shizuoka Prefecture, Japan, on July 11, 1921! The pair of red, 3-Sen Japanese definitives is in pretty good condition, but does have a fold or two under the top stamp. The CDS from the Shintake P.O. is complete, but rather light/faded. The receiving CDS(7/15/21) from the Okabe P.O. in Shizuoka Prefecture is superb! Noted imperfections aside, this remains a nifty piece of Taiwanese and Japanese postal history!
