Benedetto (Nino) Caroselli was an Italian painter and illustrator. I know very little about him, although he would appear to have been active in Italy as a cover artist and painter. The image below is the only one I've been able to find after a quick scour of the internet. He also produced at least one book cover (Angelique and the King by Sergeanne Golon, J. B. Lippincott).
For the UK Nino Caroselli produced hundred of covers for the pocket libraries published by Fleetway. He first appeared in 1959 as an illustrator for Top Spot but very quickly established himself as a cover artist on Super Detective Library, Thriller Picture Library and Cowboy Picture Library. However, it was his work for the war libraries that would keep him busy for many years during the 1960s. Here's a small selection of some of his covers for the early issues of Air Ace, all from original artwork. Some of these will, no doubt, be making an appearance in David Roach's Aarrgghh! book, coming out from Carlton in October.
