push-up
four injection molded semi-rigid plastic pieces constitute the circa tall figure which features printed accents on the dress and hand-painted details on hands, face and neck, hair, sunglasses, microphone and inserts in the trouser legs. molded as one piece, the upper body of the figure including a static head is the most prominent part. the right arm with hand and microphone is also molded as one piece and attached to the upper body piece at the right shoulder by a snap-in joint with a square connector which keeps the right arm of the figure in a static position relative to the upper body piece. the lower body piece consists of the pelvic area and both legs molded as one piece. at the waist of the figure, the upper and lower body pieces are connected to each other by a flexible metal spring joint, as are the left arm piece and the upper body piece at the left shoulder. both threaded connectors of the spring joint at the left shoulder of the figure are recessed, hiding the spring mechanism of the joint. the threaded connector of the lower body piece protrudes upward but the spring joint mechanism at the waist of the figure is concealed by a connector deeply recessed under the waist and belt portion of the jumpsuit which constitutes the bottom portion of the upper body piece.
