There were Grateful Dead comic books but I don't remember there ever being a kids cartoon.
D'Angelico guitar is also an auction item, I imagine those are either starting bids or what it is expected to sell for. A lot of times auction items owned by celebrities command a much higher price than expected, a low starting bid may be an incentive to overbid. I don't think this is one of the high end D'Angelico archtop boxes and that may be reflected in the price but if someone threw down big bucks for Jerry's old toilet you never know... There are some hefty auction fees, too, but they go easier on you if you can afford to spend over four million on an item

I grew up near where D'Angelico's apprentice Jimmy D'Aquisto had his shop. A friend used to hang there and help him clean up, pack string orders etc, I would go occasionally to hang out and watch Jimmy work. In around 1972-73 Jimmy finished a guitar but the person who ordered it decided to pass. I was offered the guitar for $1,000 which was at that point in my life an astronomical sum to pay for an instrument. I sure wish I had been able to take advantage of the offer.
