The first Hetman sheet was printed
in Kyiv over a sheet of 1988 one-kopek stamps (Scott #5838).
According to Val Zabijaka, a U.S. authority on Ukrainian stamps,
these were originally printed without postal approval, so the post
office officials confiscated the entire print run.
"For a time, they did not know what to do with them." Says
Zabijaka. "Then they asked the president of the philatelic group
and me -- I was in Kyiv at the time -- what to do with all of these
sheets. Both the president and I recommended that they sell these
sheets to collectors. This was in late June 1992. Nothing was heard
until December of that year, when these sheets were released to
collectors with an official Kiev Post Office rubber stamp, marking
them as a philatelic souvenir."
