We have collaborated with Transport for London, the government body responsible for London's rail networks, including the London Underground, DLR, London Overground and all the trams and buses that travel around the UK's capital city to produce a series of puzzles and games. Transport for London's poster collection covers over 100 years of graphic art and contains some of the best examples of posters as an art form anywhere in the world. This 1000 piece puzzle celebrates some of the most iconic and memorable posters from the collection, spanning a range of subjects, from the transport system itself to famous London attractions. As with all Gibsons jigsaws, we use 100% recycled puzzle board, paper and work with the best artists from all around the world. The beautifully illustrated pieces are designed to fit perfectly together; in fact, we use the thickest puzzle board on the market. Everyone loves a Gibsons jigsaw, even Her Majesty the Queen has been spotted with one. Specifications T
