This is extremely rare, it's not clear how many were produced, but there is no sign of another copy online so it must have been a very limited print run. 
 
Publisher's description:
 
DRY MARKER MAGIC! is an exciting book in which the author, Ron Gilbert, introduces the reader to the little used principle of this medium for magical purposes.

Within these pages there are some sixteen different ideas and routines, covering the interests of most magical enthusiasts.

From close-up and pocket tricks, to stage effects and childrens entertainment, Ron presents an effect that will appeal.

Most of all, each trick is adaptable and hopefully, will give the reader many happy hours of pleasure, both in using the effects as published or experimenting for themselves. Maybe further great ideas will be developed by you, the reader. Who knows?
