This 1975 Springbok 500 piece jigsaw puzzle is titled Unidentified Fantasy Objects, an image of floating bubble or marble like spheres in pink, turquoise blue, purple, and black. It's part of their Grand Master series - more challenging because the pieces appear to be all the same shape. Finished size is 20-1/4 inches square. The puzzle has been worked and is guaranteed complete. The box has one taped lid corner and some light edge wear as shown.
