Artmark Charity auction of the Christmas Trees Festival, for the benefit of Save the Children Romania Organization #386/2020. The artwork challenges us to decipher on our own this binary code that stands as the basis of a surprising composition. It reminds us of a seemingly warm theme that becomes intriguing by the presence of a famous character (Grinch) who hijacks the perfect image of the winter holidays by stealing its colours. Through volume and spatial effects that have become specific to Op art, the artist has built imagery of one of the most elegant and dynamic Christmas holidays.
