Jim Riser’s Amazing Solid Cup: This is 45 years old and very scarce!

From Sun Magic in 1973.  This is a chop cup type routine that ends with a solid brass cup that weighs 6 pounds!  That is right. 6 pounds!  Comes with original instructions and is highly collectible as it is extremely scarce in this large size.  Requires some slight of hand ability if  you are going to perform it   Great addition to any cups and balls or chop cup collection.  Can be polished if you wish but I have left the original patina. Try to find another!
