JULIEN'S AUCTION, New York City. Catalogues for the 19 May 2018 auction in New York. There are two catalogues:

Juliens's Auction 2018 Music Icon Bob Dylan Music Icons, 254 pages. 4 pages of Dylan items, including an handwritten Blowin' In The Wind ($50 000 - 70 000).

Juliens's Auction 2018 Robertson Bob Dylan Robbie Robertson, 52 pages. The Fender guitar sold by Robbie Robertson and used by Bob Dylan during the 1965 and 1966 tour is the star the catalogue; it was sold for $490 000.
   Dylan used the Tele during the recording of “Blonde On Blonde” and it was later used by Robertson during much of his time with The Band, including him playing it during the recording of “Music From Big Pink and “The Band” (Brown Album). Over the years the Telecaster has gone through a plethora of changes having been stripped of its original black finish, being re-routed to accommodate a humbucker pickup in the neck position and being fitted with a Bigsby tremolo arm. In fact, there’s not much of the original guitar left! (information: bobdylanisis.com)
