This is the legendary puzzle binder of pioneer collector Gregory Grant. This binder contains all 29 vintage puzzles, a number of which are extremely difficult to find and almost impossible to find in this condition. This is particularly true of the OPC puzzles, the Cloth series puzzle and the 2nd UK. The 1st and 3rd OPC "light" puzzles are perhaps the toughest. The 3rd OPC puzzle with black border is extremely particular. Checklists very often have wax stains on them that cannot be removed. These are all clean except for a very minor spot on a couple of the 2nd UKs. It took Greg more than 10 years to complete this binder and to upgrade to this condition. At this point it would probably not be possible to piece another collection like this together.
