NEWNES PICTORIAL KNOWLEDGE

ده جلدي - مصور Newnes' Pictorial Knowledge 10-volume edition, General Editors R.H. Poole and Peter Finch; Associate Editor Enid Blyton; Technical Editor E. Molloy; Art Editor A.H.J. Humphreys. Complete set in excellent condition, original binding in red with gold title and text on spine, illustrated with many black & white photographs and several plates in colour. Edition no. and publication date unknown but has reference "N.P.K. 5. W.P. 3210/52"; N.P.K. standing for "Newnes Pictorial Knowledge" and W.P. standing for "Whitefriars Press", so my amateur interpretation of this is Edition 5, printer's title no. 3210 published 1952?
