This is one of my all times favourite interlock puzzle.It resembles to the normal known 3 chain ring that intersect together only but in diagonal way!
you can find more pictures or info in my website www.puzzzlevision.com It was my entry in the international puzzle design competition IPP 23 Chicago 2003
The pictures are from the actual puzzle for sale.
It is made in 2005.It is signed and in great condition.It is my own personal copy from my display.It comes with a certificate.
I give this due to a sudden surgery that my best man's son had to do for a tumour removal.
It is therefore for a cause of collecting whatever is possible in money to help this difficult situation that they are now.(every dollar/euro counts)
Thank you very much in advance!
