This quirky colouring book is by Singaporean artist William Sim. I purchased this book on my Singapore trip. This colouring book is full of whimsical line drawings of Singapore, portraying popular places, cultural icons, and everyday life of this island metropolis.
I have coloured in these pictures with a variety of mediums. See my Book Review: Colouring The Lion City, for more details on how I coloured these pictures.
