Sinestro first appeared in Green Lantern #7, published by DC in 1961. That places it in the Silver Age.
Why this issue matters
A disgraced Green Lantern of sector 1417 turned Hal Jordan's greatest enemy, and the template for every evil counterpart with a yellow ring since. Created by John Broome and Gil Kane, his stock rose again with the Sinestro Corps War and Mark Strong's turn in the 2011 film.
