Abstract
Herbig and Mendoza1 have suggested that three Wolf-Rayet stars may be members of the young association Cyg OB2 (VI Cyg). From UBV photometry, Reddish2 has found that they are heavily obscured and has argued that most of the reddening would be caused by circumstellar dust shells. As part of a wider programme of study of diffuse interstellar spectral features, the brightest of these Wolf-Rayet stars, WR2 (V=11.8), was observed, and the results are presented here.
