After intense public demand, and for the first time on the interweb, I proudly present the "Official Clue Card" for the classic 1960 film Scent of Mystery.
Actually there was no public demand, and this card is from the 1985 showing on MTV which you could purchase for a buck at 7-11 stores. It's sort of amazing that MTV ran a rather dull and obscure 25 year old (at the time) mystery movie - even with the scratch and sniff card gimmick. They'd never run such a film today, but maybe they could try a scratch and sniff version of Laguna Beach.
When the film was originally released there was a machine that pumped the scents into the theater, but from all reports it didn't work very well. I've read the machine held 50 scents, but the card only gives you 30. Looking back now I feel short changed on smells.
