happy bunny

Hi, when I was a child, we used to have two volumes of a collection of fairy tales. These were large books, hardcover and where grey in colour. The illustrations look like they were water colours. My mum said she bought them in the late 60s early 70s in the UK. I don't know the title or the publisher, but the colsest search I found looks like "the random house book of fairy tales" though I don't think it is it, as they were two together. Does anyone know anything about them??
