This is a vintage theatre ticket stub from the Little Theatre at Colorado State Teachers College.  On the back, is written "Oklahoma Picnic Maneval?".  I'm guessing there was a production of "Oklahoma!" and "Picnic", but I am not familiar with "Maneval" or whatever the third word is. 

It is difficult to date this ticket stub.  Originally, I thought it was from 1934 or 1935 because it says "Colorado State Teachers College" and the university changed its name to Colorado State College of Education in 1935.  However, because "Oklahoma" and "Picnic" are written on the back, and "Oklahoma" was not released until the 1940's and "Picnic" in the 1950's, I'm guessing this must be from the 1950's.

"Little Theatre of the Rockies" was established at the Colorado State Teachers College in 1934 as an educational summer stock company on campus.    Colorado State Teachers College changed its name to College State College of Education in 1935.  In 1957, it became Colorado State College and then the University of Northern Colorado in 1970.
