Op Art: Postcard Colouring Book (Multilingual Edition) (Postcard Colouring Books) Paperback – January 8, 2015

Where do I start? These pictures are FABULOUS! I like the variety and the great designs. Also I really like the fact they are not already partially colored. Nice thick postcards. No bleeding through to the other side. Top quality. I just ordered two more! Love it!

I gave this two stars only because the designs are good. The problem is that even with the finest tip pen, most of the designs can't be colored. If these designs were enlarged a bit they would be fine. I hate to say I would not recommend these as they currently are 😢

Many cool designs!!! Good quality paper and easy to remove from binding

Love coloring postcards--these are such cool abstract designs!!
