No date on this, but judging by the $5 price for an adult I would place it around 1973/74. It's after the opening day of May 29th, 1971 (Inaugural Day Guest Preview link) and before my 1975 post from last month (link) where the price was $5.95.
The characters used on this brochure are a little different than the usual “Trolls and Wizard” seen on most of the paper items and souvenirs of the 1970’s. These guys don’t look like Bloop, Bleep or Blop?
This map shows its age, folks around here will notice the 118 (Ronald Reagan Freeway) is missing.
I hope you enjoyed our little detour to the Mountain today, tomorrow it's back to THE park.
