A T-Rex dinosaur skeleton wearing a ghost sheet costume for Halloween, holding a jack-o-lantern trick-or-treat bucket in its tiny arms. The ghost sheet has a spooky face with hollow eyes and a jagged mouth. Surrounding the T-Rex are carved pumpkins and candy scattered on the ground. The text 'SPOOKY SAURUS REX' appears at the top in a bold, hand-drawn horror-style font. The illustration should be in a detailed hand-drawn style with cross-hatching, line work, and texture showing the bone structure and fabric folds. Black and white line art design combining dinosaur paleontology with Halloween spooky theme in a fun, playful way.
