Vintage Japanese Rubber Stamp Star 116 by VintageFromJapan on Etsy http://www.etsy.com/listing/90836268/vintage-japanese-rubber-stamp-star-116
This was an amazing find. They are from the "昭和" "showa period" . The "showa" period is from 1926-1989 but these are about 30 years old . These were used in a school.
The stamp is rubber but it is attached to a sponge like base.
This is a unique and cool design. It is a star.
It measures about 1.5cm wide. The base is "squishy" so you can really push down and get a good image. Or you could cut off the stamp from base and use it in mixed media or for any project you can think of!
