My well-used copy has the "Penguin orange', in contrast to the more red tint as shown in the main image [#1868805]. It is the 1961 reprint (which I take to mean 2nd printing), which I purchased in a second-hand shop in Burbank, California, in 1987. I have included the Contents page, with list of the individual stories.
