Scooby Doo #1 35 cent variant

This magnificent copy of Scooby Doo #1 35 cent price variant apparently sold in a private treaty sale for $3500 by Motor City Comics.  Motor City Comics had this book (as they have had a number of other high grade 35 cent price variants) listed for sale for a long time.  Their asking price was steep but since no other copies have appeared, I am not surprised that a savvy collector finally snapped it up.  I am not certain that there is another like it.  Scooby is still very popular by the way.
