2 Espresso cone shaped cups mugs signed dated theatre music motif hc2210

These espresso cups or mugs are cone shaped with a little pedestal instead of a saucer. These are signed and dated by the designer, Linda ---- 1999. I can't make out the last name. They are from Source Incorporated. The phone/fax numbers on the bottom are to Phoenix, Arizona. The mugs are a dense red chocolate with an applied design that is reminiscent of the theatre or perhaps jazz or Carnival. These are very interesting pieces. The cups are 3 inches high. In perfect condition.
