Aquaman #37 is a desirable Silver Age DC key featuring the first appearance of Scavenger (Peter Mortimer), one of Aquaman's most recognizable recurring adversaries. Written by Bob Haney with classic artwork and cover by Nick Cardy, the issue is remembered for its striking "When the Sea Dies!" cover and strong late-Silver Age storytelling. This copy has been professionally graded CGC 7.5 Off-White to White Pages, placing it solidly within the upper-mid grade range for a book that is becoming increasingly difficult to locate in attractive certified condition. Aquaman keys have seen renewed collector interest in recent years as fans continue to assemble complete Silver Age runs and pursue first appearances from the character's expanding rogues gallery. Nick Cardy's dynamic cover art remains one of the highlights of the Aquaman series, and Issue #37 is widely regarded as one of the stronger covers from the late 1960s. The combination of Silver Age pedigree, key first appearance, and attractive presentation makes this an excellent addition for both Aquaman specialists and DC Silver Age collectors. Professionally encapsulated by CGC, this copy offers long-term preservation and investment-quality presentation.
