From the Book People blurb:
Children, especially those with an interest in art, will love joining young Katie as she manages to explore a variety of famous paintings by climbing inside them. The Katie Collection is full of fun and educational reads that see the happy little girl discover more about sunflowers, dinosaurs and the Mona Lisa, amongst many other delights. James Mayhew’s long-running series of picture books are steeped in culture and are perfect for parents and children to read together at bedtime. Wonderfully illustrated, they will help introduce your child to the joy of art!
I think these books are really good, and Amazon agrees – lots of 4 and 5 star reviews for them.
(Clicking on the pictures will take you to Amazon, where you can read more about them, have a look inside and buy each for only a couple of pounds if you miss out on the Book People deal – they went quickly last time!).
I don’t have all these books, only a few but I love them and want to gradually purchase all of them.
Sorry to just now get to your info about your blog address change. I’ve have been busy with a new job and my husband’s and oldest daughter’s illnesses.
I have you listed in the sidebar of my current art blog. Since my official home educating days are over and I’m not posting much at my home education blog I spend more time at my art blog and incorporate home education info/ideas when I can.
Blessings!
I’ve awarded you Clare
