[Unused, Rare] Second Series Showa Stamp "Maeshima Hisoka" with 20 stamps with selvage, Misperforation Error Stamp issued in 1951. Looking from left to right at the perforations on the upper part of the lower row, there is a misalignment. The perforations on the left side overlap the design. My father-in-law has been collecting these for many years, and I am listing them to organize his collection. Please take a look at the photos and purchase if you are interested.
