What a historic find!  Discovered at an estate sale this unused 1878 (Scott #1) or 1882 (Scott #4) China Imperial Large Dragon Stamp was apparently previously hinged perhaps in a stamp album?  It was discovered separated in a secure, separate sleeve.  It is indeed made of thin paper.

     It appears in near mint condition except for dark spot on back where it was apparently hinged.

    U.S.P.S. shipping and insurance is $6.50 within the U.S.  International shipping is via the E-bay International Shipping Service.
