The Saturday Book (1950) 10th Anniversary edition has this quite modern sounding interview/ blurb printed on the inside flaps of its jacket. It was edited by Leonard Russell who probably wrote it. There is a 1000 to one chance it was written by George Orwell a one-time contributor and no stranger to advertising techniques..
Inside flap reads:

A.Conservatively, as a master piece.
Q.H'm, any particular favourites among this year's contribution.
