Series 4 consists of scripts for a number of plays produced by the Little Theatre of the Rockies between 1948 and 1995. The scripts appear to have been part of the LTR script library, and several are identified as belonging to specific actors or faculty including Helen Langworthy, Welby Wolfe, and J. Stevens Girault. In addition to the marginalia found in these well-worn scripts, there are rehearsal schedules, blocking diagrams, casting information, and set sketches for many of the plays.
