Nana's Mother was published by Avon Books in 1950. The title is, unusually, not an Avon creation. It is seen on the title page of the first American edition (Philadelphia: T. B. Peterson, 1879). But the cover is most definitely an Avon - a 1940s Hollywood version of mid nineteenth century France.
L'Assommoir is the seventh in Zola's Rougon-Macquart cycle of twenty novels, published in 1877. The Oxford edition is approximately 2 1/4 times longer than the Avon.
