David A. Trampier was an artist and writer whose artwork for TSR, Inc. illustrated some of the earliest editions of the Dungeons & Dragons role-playing game. Many of his illustrations, such as the cover of the original Players Handbook, became iconic. Trampier was also the creator of the Wormy comic strip that ran in Dragon magazine for several years.

The Player's Handbook is the name given to one of the core rulebooks in every edition of the fantasy role-playing game Dungeons & Dragons (D&D). It does not contain the complete set of rules for the game, and only includes rules for use by players of the game. Additional rules, for use by Dungeon Masters (DMs), who referee the game, can be found in the Dungeon Master's Guide. Many optional rules, such as those governing extremely high-level players, and some of the more obscure spells, are found in other sources.
