13th edition of Observer's Pocket book on aircraft in an unusual plain and apparently unrecorded variant dust wrapper. The wrapper has no illustrations or colouring, just plain printed titles and is possibly a printer's dummy or a pre-publication wrap for a review copy (if you know better, please let us know). Various other titles from the series, ending with Lichen, listed on the inner front flap of the dust wrapper.
