From the collection of Joe Ross, well-known amongst revenue stamp collectors as someone with one of the largest revenue stamp collections in the world and author of several revenue stamp catalogues, comes this revenue stamped document from the city of Masan (??), now part of Changwon (???). Unlike with postal documents, revenue documents are usually not available to collectors of revenue stamps, meaning that this type of document is quite rare.
What are we looking at? This is a certified copy of the middle school graduation certificate of (name redacted), born in 1977. This person went to the Masan Dong Middle School between 1990 and 1993, finishing middle school in the three years middle school takes in Korea.
Masan is part of the city of Changwon, which is in Gyeongsangnam Province. Changwon is a port city to the west of cities such as Gimhae and Busan.

- ?? = check/verify
- ?? = compare (=to see if this copy is identical to original document)

It is not known how or why this document came onto the market, but somehow it found its way out of Korea (Joe lives in California).
