Marianne Faithfull had a dog named Rosie, and she appears in quite a few pictures. I'm sure there are more out there, but for right now these are all I can find. She also had a song called "Rosie, Rosie," about a girl named Rosie who ran away from home to join the "upper classes" and the singer wishes she'd come back because home isn't the same without Rosie. I don't know who wrote the song, but it was on her Loveinamist album released in 1967. The first two images were scanned by the wonderful (Diet) Coke and Sympathy, whose blog you can find under my followed blogs. Or you can just click on it, whatever.
