The “Double Bubble” name refers to the two convex glass layers. An inner bubble displays the company logo, while an outer, domed crystal bubble contains the numbers, creating a floating, three-dimensional effect. This fantastic double-bubble Canada Dry clock measures 15 inches from top to bottom and side to side, with sharp gold and red graphics on the outer bubble. It lights up easily and works well. It appears the minute hand is slightly bent, and the red second hand touches it every minute. The hour hand has a few paint chips on it as well. Some typical scratches are visible along the outer edges of the top glass. On the reverse side, it still retains both metal doors for replacing light bulbs when needed, along with minor marks from use. The CSA Testing Laboratories decal is also visible on the back. This great “Drink Canada Dry” bubble clock will look very sharp on your wall! 21543-QPQP
