The Perfect Design

I think this is one of the perfect designs in the world.
Nobody seems to know how old it really is and maybe that is a good thing because then no one can claim that he owns the right to the design and demanded to be payed for it.
This came to me as I took this one out of the washing machine and was putting it together and thought that I have lived with this design all my life an never giving it a thought how great it was.
I hope I will still find something I have not appreciated to its full extent.
