Bert's collection of actress postcards - part 1

These are all by the Rotary Photographic Co and date from the early 1900s. They were obviously purchased as collectors' items as none have actually been through the mail, although one of them has Bert's name and address written on the back:
A.C. Mackie, 15 Plumstead Common Rd, Plumstead, Kent

From top to bottom and left to right we have Miss Winifred Hare, Miss Susie Vining, Miss Doris Lester, Ruth St. Denis "Hindu Radha" (not quite what it says on the card, but results ofGoogle searches suggest that the caption is incorrect), Miss Zena Dare and Miss Maud Allan "Medelssohn's Spring Song".
