This book was a short picture book that I read in the 1970’s. I am guessing it was published late 1960s to mid 1970s.
A girl visits her great aunt or similar relative, who is bedridden and lives in a room upstairs in a beautiful old house. When the clock strikes the old lady turns back into herself as a young girl and the two girls play together and have a great time. Then the clock strikes again and she turns back into an old lady. The girl is dressed in what children would have worn in the 1890’s or thereabouts and I remember she had long black hair with a ribbon tied in it.
