Description
"Chicago L" is a modification by the computer genius Donald Knuth of a Henry Ernest Dudeney puzzle, exchanged at IPP23 (2003) in Chicago by perennial exchange participant Stan Isaacs. The puzzle consists of 12 L-shaped interlocking pieces which must be put together to form a solid square in which the lines form a continuous loop.
The puzzle is in its original felt pouch, complete with original instruction card and sealed solution sheet, as presented at IPP23.
I will ship within the US as a ground advantage (new terminology
replacing "first class") package for around $6.65, or if preferred, at
insured priority mail pricing
(likely from between
$10.20 and $12.55, depending on postal code). I am happy
to ship
internationally at cost --- typically around $17.10 for a small item like
this --- but I cannot always guarantee that overseas
packages can be insured or tracked.
Thank you for viewing my auction!
