A vintage 1970s style poster depicts skeleton hands holding books, reaching towards a silhouetted figure in a bright doorway. Text reads 'UNIX OPENS THE DOOR!'

1970s vintage comic book style illustration, retro psychedelic anti-drug poster aesthetic with detailed Ben-day dot halftone printing effects. Deep black textured background with subtle noise grain typical of 70s comic printing. Dramatic bright yellow triangular light beam emanating from an open doorway, creating sharp geometric shadows and highlights. Silhouetted human figure standing in the bright doorway opening, backlit against warm yellow/orange light, figure appears small and distant in the composition. In the immediate foreground, multiple skeletal hands and bony arms reaching desperately upward toward the light source. Each skeletal hand is grasping a thick Unix system manual or programming reference book instead of syringes. The skeleton hands should have detailed anatomical bone structure - visible knuckle joints, finger bones, metacarpals, radius and ulna bones in the forearms. Bones rendered in pale gray-white with darker gray shadows in the joints and crevices. Each hand grips a different style of technical manual - some thick hardcover Unix books, some paperback programming guides, with visible book spines and covers. Bold retro lettering at the top reads 'UNIX OPENS THE DOOR!' in classic 1970s comic book typography. 'UNIX' in bright red-orange gradient with yellow highlights and black drop shadow. 'OPENS THE DOOR!' in bright green gradient with darker green shadows. Letters have that distinctive 70s comic book 3D block letter effect with beveled edges and See more
