In the olden days before satellites and before CDs, radio shows were sent out on the media of the time, commonly vinyl records.  This is what you would have heard over the air in 1985 (specifically the week of in mid-September 1987, the weekend of September 12-13 or "week 37" of that year) and includes the entire show, some national commercials on the record, and empty space (rills between tracks) where the station would run its own local commercial.  Includes the cue sheet offered to the radio station to keep track of the program, clean and unmarked and looking like new. The records were played a few times in total and show no scratches, a few light scratches may be audible in the outside rill before the program begins but the vinyl is clean and plays like new.  They've been in storage for 27 years.  No chips, dings, craters, pimples or warps, just two vinyl records with a half-hour of program per side for a total of two hours.  There is no cover (there never was), just what radio stations received for broadcast, stored in plastic sleeves.  Exactly what you heard on the air 27 years ago. Or if you missed it that week-- here's your chance. :)
I am down to about three more programs after this week, which are in less than perfect shape so this is nearing the end of my Doctor Demento program stock.  Last chance time.
Note I will be listing two of these Demento programs simultaneously.  If you win both I will ship them both together for an additional 50¢ ($3.67 for both). 
$3.17 Media Mail for a single, $3.67 double, shipped in a Uline professional vinyl record box.  PayPal/US only please.
