Arneson Game Collection Up for Auction

From ENWorld:
Dave Arneson, co-creator of D&D (other other, of course, being Gary Gygax) had - as might be expected - quite a collection. These items are being auctioned, and include, according to GeekDad, "..his original gaming dice. His original Dungeons & Dragons and Blackmoor campaign manuscripts. His first printing, woodgrain boxed set play copy of D&D. Letters from Gary Gygax. Other letters, notes, documents, artwork, photos, cartography, rare wargames and hand-made models and miniatures. And more."


There are about 10,000 items in total, and the series of eBay auctions will begin on Sunday, May 6th.

• His original gaming dice.
• His original Dungeons & Dragons and Blackmoor campaign manuscripts.
• His first printing, woodgrain boxed set play copy of D&D.
• Letters from Gary Gygax.
• Other letters, notes, documents, artwork, photos, cartography, rare wargames and hand-made models and miniatures.
• Published games, game accessories, periodicals, and books.
• Arneson’s Smith Corona: Mark IV typewriter.
• A set of lead crystal goblets etched with Arneson’s family heraldry.
• A model ship made of metal.
• Unpublished manuscripts that did not make it into the final draft of Dungeons & Dragons that date as far back as 1973.
• Older items from 1971 and 1972 “dealing with the Blackmoor campaign and the Castle itself,” which may reveal secrets about the game’s origins.
• Runs of Gygax’s Castle & Crusade Society and Domesday Book newsletters.
• Arneson’s Corner of the Table newsletter which discusses his various campaigns, including his Blackmoor exploits.
• Arneson’s personal copy of a book he created called “Dungeonmaster’s Index,” an index of all monsters, spells, rules, and magic items, which was published under his own name and without a license.
• Arneson’s locked briefcase (contents unrevealed).
• Arneson’s 1959 game of Risk.

This will be a series of auctions over the coming months, each containing some 200 items. The first auction on Sunday, May 6, includes several rare wargames and role-playing games owned by Arneson, as well as inscribed and autographed copies, editorial and review copies of products, items from Arneson’s library, and his personal play copies. Among the “many special items” are a series of Empire of the Petal Throne books and journals autographed by the late game designer M.A.R. Barker, who died in March of this year.

You'll find the auctions on eBay at this link, though there won't be anything there until May 6th.

 Later in the posts it states that the IP will stay with he family but the documents will be sold, that intrigues me and I wonder a few things:
1) Is that legal?
2) Is it enforceable
3) Will that reduce the value of these documents, due to their investment value dropping.


As always, post here of on my FB or email me what you think.
