104 drawings with music notation symbols, many of which have been reprinted in magazines and as program covers. Perhaps the best known is the Celestial Music for Imaginary Trumpets, which ascends 103 ledger lines above the treble clef. Originally published in English only, a fourth printing of the volume was published in 2001 with titles in English and Spanish.
