Groovy / Crescendo

A wide, landscape-format backglass with a busy mid-1970s airbrushed pop-art scene in bright red, yellow, blue, green and black, framed by a thin white border inside a wooden cabinet edge. Two white rectangular score windows with dark surrounds sit left and right across the upper third, each showing four black digit faces; a small '2 PLAYER' label and a cursive 'Gottlieb' signature sit between them. The centre is dominated by a large diagonal white bubble-letter logo with a black outline, the letters stacked and slanting down to the right. The artwork shows a psychedelic hippie festival: a long-haired male guitarist in a red cap and green-and-yellow tie-dye shirt at far left, a tall woman in a white polka-dot mini dress and platform sandals singing centre-left, a woman in a white cap and striped top behind her, a bare-chested long-haired man, a seated woman in a red-and-white striped dress, and at right a blonde woman in a striped dress and a shirtless man with sunglasses sharing a round green cocktail table with a tall green drink and a lime. Two upright cabinet-like boxes read as speaker/amp boxes in red and blue. Orange and green flowers, a harp, a grey poodle on a leash, dancing silhouettes, striped black poles, flags, a yin-yang circle and a rainbow arc fill the background. Bottom-left is a red player panel; bottom-right a slogan. Bottom centre carries a maker line in black-outlined caps with a red oval in the middle.

A square, brightly coloured cartoon backglass photographed in its white wooden frame against a rough stone wall. Four rectangular mechanical score windows sit in a 2x2 arrangement, each showing three white digit windows reading 0,0,0 on a black background with a red border. The centre carries a playful title of chunky, cartoon lettering - a large pink-outlined G above a small orange plaque, then oversized blue and pink bubble letters spelling BOY, with a yellow ringed zero and a blue D shape beside them. Behind everything is a hot pink and purple field scattered with coloured round balloons or lamps, a yellow butterfly on the left, a big blue arrow on the right marked SPEED, and number balls (a pink 8, a yellow 20, a blue 40, a green 20) floating at the corners. In the lower half a blonde woman in a pink dress dances at a jukebox-like cabinet; a man in a hat plays a keyboard organ at the lower left beside two small seated figures at a table; at the lower right a man in a white shirt and red cap sits at a small round green-topped table under a lamp, next to a large blue horned creature. A white strip along the bottom edge carries small black copyright lettering.

A painted, 1960s-style psychedelic-pop backglass in hot magenta, purple, orange and yellow. The word PSYCHEDELIC is spelled in enormous chunky bubble capitals that run diagonally down the upper-left and centre, in red and purple panels with thick white and black outlines. Across the top hangs a row of five round stage spotlights on a bar, with dark silhouette dancers below them. Top right sits a white rounded-corner window labelled SCORE containing the black numerals 72,410. Seven human figures crowd the lower half around a tall black speaker cabinet with an orange cone: a blonde woman in a white dress covered in big orange polka dots stands centre-left with both arms outstretched; behind her two figures recline on a tufted green sofa; a striped-shirted figure with a white cap sits at the far left edge; a person in a yellow-green striped top and dark cap crouches low left; and at the right a man in a white shirt and rust trousers kneels facing a seated woman in a red dress who holds a small glass. Playing cards, daisy-like flowers and orange blossom sprays are scattered as motifs. A small white panel at bottom right reads PREVIOUS HI SCORE.
