Embossed Am Tel & Tel Co—Two Piece Transposition (top and bottom). The bottom is just a plain old blue aqua, but the top is nicely endowed with amber and milk swirling. The wild amber swirling is clearly seen in the pic, but the milk is washed out due to the back lighting. If you look closely (use the "View Original" feature) you can see some of the milk banding flowing across the lower portion of the umbrella. Base lighting would be the ideal method for displaying both the amber and milk features. Find a matching base someday and this would be one heck of a wild tramp. $150, plus actual shipping. That's about equal to the value of a common purple diamond tramp, yet you get something totally unique!
