A sleek black cat with luminous green eyes sits center stage against a deep blue ground, one paw raised toward a golden fish pouring from an overturned pitcher while a glass of pale cocktail awaits below. Bold golden lettering reading "MIX YOUR DRINKS WITH CATZ BITTERS" frames the composition in a style evoking early 20th century advertising graphics, with warm mustard tones and linear details that give the feline figure an art deco sensibility. Printed on smooth white card stock and made to order, artwork on the front, blank inside, envelopes included in every set. A handwritten note that arrives as an independent artist's work.
