2011 Optical Illusion Calendar
Last year's Optical Illusion Calendar was very popular, and sold out really quickly. We expect this 2011 calendar to be just as popular! 365 pages, each with a different optical illusion, printed in full colour. 11.5 x 16.5cm.
Please note - this calendar is produced in Holland, and the small amount of text in it is in Dutch. The illusions however work in any language!
Was £18.99 - now just £9.99. Limited Stock.
