One of Buckler's covers from DC for SECRETS OF HAUNTED HOUSE 32, Jan 1981, inked by Bob Smith.
Buckler covers on
SECRETS OF HAUNTED HOUSE issues 32-40.
Bob Smith is actually one of my favorite inkers on Buckler. Some stories Smith inked over Buckler are
JLA 190 (Buckler pencils in 188-191, from 1980-1981) and the above linked full 8-page story from TIME WARP 1, that I found on posting it, was miscredited to Dick Giordano, but was actually Bob Smith! 37 years later, the proper credits revealed.
