244pp + cat VG/none First edition, presentation copy inscribed and signed by the author. Original editorial black hardback, lettering on spine, minimal wear on boards, spine lightly sunned, occasional spotting on edges, overall a very good and nice copy, tight and clean. Particularly interesting in the chapter dedicated to television; Sidney Alexander Moseley was a radio critic and journalist, friend and closely associated with Baird, championing Baird’s mechanical television system. This is an original edition and not a modern reprint or reproduction.
