Sludge 10 unused cover ny Lopresti

Done in 1994
Sludge was published by Malibu Comics.
After Malibu was sold to Marvel Comics, Sludge ceased publication.

Sludge was a character patterned after the other Muck Monsters that preceded him such as the Heap (1942), The Glob (1969), Swamp Thing (1971) and Man-Thing (1971). They all in turn could have been inspired by the short story 'It' by Theodore Sturgeon (1940).

Sludge was created by Steve Gerber, Aaron Lopresti and Gary Martin in 1993.

This cover was not used and the character on the cover did not appear in the comic.
According to Aaron:
After the 2nd issue of Sludge, Gerber did not turn in scripts in on time. By issues 6 - 9 I was plotting the issues and then Gerber would use my plots to create scripts. When the 10th issue rolled around, he once again did not turn in a script. So I created a character called "Dusk" and I was going to write and draw that issue. Gerber then showed up with a two part script, so my issue 10 was scrapped and they used Gerber's story. Which ended up being a two part fill-in artist, while I wrote and drew a double-sized issue #12. That, of course, ended up being the final issue.
