This was an amazing find. This is from the "æ˜å’Œ" "showa period" . The "showa" period is from 1926-1989. This is called "åž‹ç´™" or "katagami".
Katagami are made of multiple layers of thin mulberry paper which are bonded with a glue extracted from persimmon, which makes a strong flexible brown coloured paper.
