A little late but I was working on my new book for the last few days. Excellent book for "bad days". Full of colour, humour, lovely creatures, sun and fun... My favourite "yellow book" – yellow for me is the colour of happiness :-). Published by Éditions du Rouergue in 2002, made by Séverine Assous and Laura Jaffe. 
Have a fun watching it! 
By the way, could someone who knows French be so kind and tell me what is this book about – (because maybe it's not so happy as I think only watching pictures ;-)
