This is a great "printing" effect or a kind-of mis-made silk effect.
A silk hank with a black dog pictured changes into a silk with a white dog pictured on it. Then the two silk hanks 'morph' into a picture of a white dog with black spots; a Dalmatian!
Included are two nice routines written by Duane Laflin.
Comes in a set of three 18'' top quality silk hanks.
