A manila envelope encloses the treasure; the postmark is CA, Sep 29, '88. The return address reads Lincoln Enterprises, Inc.
The contents are printed materials: large sheets of paper are folded to fit into the 9x12 envelope; there are enough sheets to poof the envelope up to an inch of depth. A peek into the end of the envelopes shows line drawings, with solid and dashed lines, and arcane markings, appropriate to the trade of those who put this treasure to its best use.
