Today, I'm posting a copy of the invitation to the 60th anniversary celebration of Knott's Berry Farm, which was held on June 14, 1980.
The invitation was made in the shape of a diamond. The outside was a gate fold held together with silver foil sticker on which was "The First 60 Years". The back of the outside has a picture of Mr. and Mrs. Knott.
When you open the invitation the inside panel has another silver foil sticker on it and printed on it is "You Are Invited to 1980's Most Fabulous Party" and the Knott's logo. Then, a plastic "Diamond" glued on below the logo, under that is printed "Diamond Jubilee 60th Anniversary 1920-1980".
When you flip up the inside center panel on the back is a picture of the original berry stand and a parchment sheet that was folded and stapled inside print on it is the Knott's "K".
Flip open the parchment sheet to reveal the actual invite information.
Under the invite page is the program for the day, concluding with the 1980 version of the ice show "Those Wonderful Years".
