Description

⟬ Metal Fortnight ⟭———04. Doug Engel, Wil Strijbos - Black Hole (Bits & Pieces version, 1999)



i think of this as an engineer's puzzle.  it's something of a Columbus Egg: it seems like an impossible object, but has a very simple and practical solution.




♫: 


â–ª everything i have is in the photos.


â–ª buyer pays shipping, calculated after the auction.


â–ª shipment is by USPS Priority Mail, insured for the full sale price, and trackable.


â–ª payment via PayPal only.


â–ª all puzzles in my collection have been kept out of sunlight, in a humidity-stable room or sealed plastic container, away from pets unless they can solve them, and in a non-smoking household.



thank you for looking, and good luck if you bid.
