1962/07 Green Lantern # 14, page 12 by Gil Kane & Joe Giella. First appearance of Sonar.

This page was published in July 1962, penciled by Gil Kane and inked by Joe Giella.

Featuring the first appearance of Sonar, in the story entitled "The Man Who Mastered Sound". As a kid, I loved Sonar's tuning fork gun and thought it made him a worthy adversary to Hal.

This page is in the best condition of any silver age page that I own, having been framed behind UV glass, probably for most of its existence. On the back side there is a for sale price of $6.50 that is date 1962. Can you imagine?
