I don't use grail often, but this one qualifies.  Scooby Doo #1 printed in Mexico by Novaro.  This is the Spain variant which is evident by the Ptas 7 in the upper left corner.   The Mexican Edition without this is impossible to find. This one is extremely rare and highly sought after by Scooby Doo 1 collectors.  I have only seen this copy for sale and only a couple of other copies in private collections.  The book is in lower grade.  I would call it a 2.5 to 3.0.  There is writing on the cover.  Cover is attached. Pages are off white.  Chiquilladas #328 printed May 1972.  I am pretty firm on the price as I doubt I will see another.
