Compulsive anthologiste Richards (Great Musicals. . . . Best Mystery and Suspense. . . . Best Short Plays. . .) now seizes on a new organizing principle--winners of the American Theatre Wing's Tony Award for ""Most Distinguished Play"" (not musical) of the Year. Only 10 of the nearly 30 winners since 1948 have been chosen for presentation here, and each is given its own brief preface, providing excerpts (favorable ones only) from Broadway opening night reviews, production history, and biographical notes on the playwright(s). Disappointingly, Richards' picks include some of the most anthology-prone plays of our time--Mister Roberts (the first Tony-winner), The Fourposter, The Rose Tattoo, The Teahouse of the August Moon, and The Diary of Anne Frank--as well as the somewhat less ubiquitous Luther, The Subject Was Roses, Borstal Boy, Sticks and Bones, and, the most recent selection, Joseph A. Walker's The River Niger (1974). The collection will also feature a short statement on the history of the awards and eight pages of black-and-white photographs.
