The LSD (Ludicrous Systems Development): A Psychedelic Happening Construction Kit was produced in 1966 . A centerpiece of our new Countercultural Ephemera Collection, this game kit represents a brief moment in time when LSD usage was legal and party games intersected.

It’s a psychedelic hippie puzzle with no rules and no solution. There are twenty game pieces printed with pretty groovy décor. Cards included were not identical from set to set, so while you never knew what you’d get, it would definitely be psychedelic. Alas, the kit only had a brief moment in the sun during the Age of Aquarius. The game was discontinued after LSD drugs and dropping acid became illegal to use.
