Unpostable Wishlisted - Magic Tree House - Audio Cassettes

My purchase of this (pre-owned) involved a surprise -- the previous owner perhaps owned multiple sets of audio cassettes, and inadvertently happened to have placed a tape from a different set in this, given that the sleeve/wrap has artwork indicating that the (2) enclosed audio cassette tapes are Books 31 & 32 (Summer of the Sea Serpent -and- Winter of the Ice Wizard) -- however, in reality, the (2) enclosed audio cassette tapes are Book 3 (Mummies in the Morning), Book 4 (Pirates Past Noon), and Book 32 (Winter of the Ice Wizard).

Books 3 & 4 are on one of the audio cassette tapes, and Book 32 is on the second tape.

Each of these is wishlisted, when it comes to the respective original sets containing these tapes.

Anyone interested, please send me a PM.  2 credits.

Thank you...
