DC Comics Ink-Wash Covers ~ The 2nd Wave
By the late 1960's about the only title that occasionally featured an
ink-wash cover was the Kanigher edited title G I Combat...when
Carmine Infantino took over at the helm of DC he renitiated the
experimental use of wash covers and other production techniques on
their covers, including using mezzatint screens on ink-wash
illustrations which gives that scratchy feel to them...

Here's a batch of them...
