I'm always a fan of more imformation. Take this entry for example:
http://twistypuzzles.com/cgi-bin/puzzle.cgi?pkey=1501Should this be broken into 2 entries in the Museum?
One entry would be for the Caution Cube and list Shapeways as the Producer and list Shapeways original price. The other entry would be for the Gear Cube and list Uwe Meffert as the Producer and list his price. It would have a different year of release, etc. Maybe both entries could mention (or link to) the other to keep the history clear.
In cases of unique puzzles... be it a one-of-a-kind or the first signed prototype that was sold on eBay (or other auction site) I wouldn't mind seeing a record of the value of some of these very rare puzzles. Sort of like this:
http://twistypuzzles.com/cgi-bin/puzzle.cgi?pkey=1477Though I see it says "The first auctioned for $2250 on Ebay in 2008." And when I check
here it looks like it sold for $2275. Not sure why the difference at the moment. But I'd find it interesting if the Museum could sort rare puzzles like this by their sale price.
Just an idea I wanted to throw out there. Granted you give an inch someone like myself is going to want to take a mile.
