Much of what is described as post-modern or contemporary art leaves me baffled. The ones defined by simplicity in particular, such as shown here that probably hang in galleries and fetch millions, are no more art than this cache! In the eye of the beholder and all that I guess.
I hope you will admire and appreciate the simplicity of this cache, take some time to study the subtle hues and physical features, and feel the emotion of the artiste who created it .... :-) But unlike the above gallery pieces, you may and really should touch this one and leave your mark!!
