Through the main span of the bridge we can see the towering "Cheesegrater" building, and to the right of the bridge is a distant view of the historic Tower of London. The photographer has used a slow shutter speed for this shot, making some of the river traffic look almost ghost-like. This puzzle would be a challenging project for puzzle "professionals". High quality 3000 piece cardboard jigsaw puzzle. The finished puzzle measures 121 x 80cm when complete. Suitable for ages 12 years and up. Made from strong premium grade cardboard, with linen finish print to minimise glare on puzzle image.
