Adele Werber and Doris Laslo - Illustrators

My daughter loves the book "Kattekillingerne, som gemte sig for deres mor" (The Kittens That Hid From Their Mother) that I bought second-hand when she was 4 years old. I have no information on the illustrators - of whom there were two - Adele Werber and Doris Laslo. Nor have I any real information on the author Louise P. Woodcock except a few listings on books she wrote. This book was written in 1957.

These are some of the sweet pictures in it.
