Early Charles Lotton iridescent blue/silver cabinet vase, 1974

Another item from last week's Flea Market (antiques show), this sweet little cabinet vase by Charles Lotton captured my attention for its cobalt blue ground, incredible silver iridescence on the top half, cobalt iridescence on the bottom. 2.75" tall, signed Lotton 1974. My lovely wife claims all the blue glass I buy - I may fight her for this one!
