I bought 3 of these colouring books as gifts and was amazed that each destination had their own colouring book. I’ve given the Bristol one to my daughter for her birthday and she was thrilled (she turned 44!). So no age limit on these and she was pleased to recognise all the familiar places that she knows well. The other two are Christmas gifts but I will expect a similar reaction. Also ideal for anyone laid up who doesn’t have the energy to read a book but quite able to colour familiar landmarks - ie the elderly or someone in hospital or recuperating - who doesn’t love to colour in ? - and keep it in the lines. An ideal gift 👍
