The last I heard was that it might go to 500,000", continuing to talk about the Famous Five Club, and hoping "to put out some really worth-while ideas for children. They do so love to follow what I say - and tell you the truth, I want to use the enormous influence I have now, to guide the children, as well as to entertain them", signed vertically downwards in the margin of final f.; 3 typed carbon copies of letters from Holbrow to Blyton, dated 13 February, 16 February and 2nd March 1953, each 1p., 4to, minor pin hole marks to upper margins; and a photograph of the author, v.s., v.d.
