Too much dirt and grain in that for a modern home video transfer, still would make a nice rarity i mean if you were rich enough to buy it.
Not too many years ago a print of star wars in 35mm IB tech was at auction for the starting bid price of 2000 dollars. It went for like 4000 but the bidder did not pay and the item was removed and never re-listed.
The gentleman who owned that print is the same guy who loaned it to the place in Baltimore.
For that price of song of the south you could purchase the entire original star wars trilogy and in LPP too on 16mm. Or at least a few years ago you could now i think because of Lucas tactics these items prices will skyrocket.
