Another old-ass skin for GoldSource engine Counter-Strike, comes with GUI icon too (however I'd advice you to be careful when installing it, and even better yet make some backups before proceeding).
Included the original render (yay!) just to make it look more old stylish in this new era of skinning.
P.S.: If I missed any other author then please correct me and I'll add them to the list.
