I now print out the rule for Media Mail service and mark the section
about piano rolls and label the roll as a player piano roll.  The
Dallas postal station has now rejected and lost several of my rolls.
One box had six original "O" rolls and stayed lost for four weeks,
finally arriving "Postage Due".  A Wurlitzer roll went out and arrived
"Postage Due."

So print out the rules on the post office site and include them for
the inspectors.  Maybe add a membership application for AMICA.
