Highly detailed vintage retro vinyl sticker illustration of a sleek crow standing in profile with head tilted sideways, one beady eye glinting with mischief, holding a shiny vintage key in its sharp beak, talons gripping a small branch. Intricate feather rendering with overlapping scale-like patterns, fine parallel hatching for sheen on the back, dense cross-hatching for the chest, individual primary feathers on folded wings clearly defined, detailed beak texture, sharp claw details on branch. Small sparkle marks around the key indicating its shine. Bold curved arched text "PROFESSIONAL" above the crow following a half-circle path and "TROUBLEMAKER" curving below in matching half-circle, in bold condensed slab serif font. White background, professional black ink illustration, vintage engraving aesthetic, no border, no frame, isolated illustration centered composition.
