Série Blême

This Serie is a collection of crime novels and thrillers founded in 1949 by Marcel Duhamel at Gallimard. Concered at the same publisher by the Série Noire to which it looks so much on the form as on the bottom, this collection is stopped in 1951. From No. 1 to No. 4, volumes are published with a green box framed in white. From No. 5, volumes are published with a red cardboard on the left vertical third of the cover and green on the other two vertical thirds. Link https://fr.wikipedia.org/wiki/S%C3%A9rie_bl%C3%AAme
