A new block calendar on year 2011 was designed at Paul Baars Design. As the calendar 2010 this one contains of 365 various optical illusions. With it you will begin every new day of 2010 year from new unique illusory image of such famous artists as M.C. Escher, Jos de Mey and Istvan Orosz or less known but not less interesting artists.
It's very valuable for me that one of my impossible figures was published in the calendar.
