- Cap and Bells
- AMT and WTF consists of posters of shows done by the Williamstown Theatre Festival and/or held in the Adams Memorial Theatre. These are posters of performances of works by George Bernard Shaw, Shakespeare, and others. Several beautiful drawings can be found on the faces of these posters.
