*DC: After #123 (‘Flash of Two Worlds’, as if you need telling), and the premier issue (#105), probably the most in-demand issue of the Silver Age Flash is #139, which featured the first appearance of Professor Zoom, the Reverse-Flash, Barry Allen’s super-swift nemesis from the far-flung future, whose appearances in the popular Flash television series have caused his early appearances to zoom (sorry) upwards in value. We are delighted to welcome the Reverse-Flash back into our inventory – though we anticipate not for long – with this attractive mid-grade copy of his debut. Clean and sound, with moderate spine edge and corner wear, but unimpaired cover scene, firm at staples and decent interior, this copy is VG- p £165.
