Swamp Thing #39 is one of the standout issues from Alan Moore's legendary run on Swamp Thing and features an early appearance of John Constantine, the character who would later headline Hellblazer and become one of DC's most enduring occult heroes. Moore's groundbreaking work on the title transformed Swamp Thing into one of the most influential horror comics ever published, making high-grade examples from this era increasingly sought after by collectors.

This copy has been professionally graded CGC 9.6 White Pages and is the Second Highest Graded example on the CGC Census, with only 9.8 copies ranking higher. Registry-quality copies of Moore-era Swamp Thing continue to command strong premiums due to their combination of literary significance, low survival in ultra-high grade, and growing demand for key Constantine appearances.

Unlike many later issues from the series, issue #39 benefits from both Alan Moore's critical acclaim and continued interest in John Constantine, making it a desirable addition for collectors of Bronze/Copper Age horror, DC keys, and CGC Registry sets.
