Vintage Collectible What's Next? by Tenyo

This one has the harder to find convex or domed spots...not the flat ones
 
A jumbo card is shown to the audience. It has one spot on one side and four on the other. It is shown again to have three spots on one side and six on the reverse. The magician proceeds to explain to the audience how the trick is done and everyone thinks they understand - that is until they find out that they have been fooled. The real surprise is when eight spots appear on the reverse side.
 
CONDITION NOTES:  There is some age and use wear, but the item still performs nicely. Packaging shows some damage, including tape residue, staining, and minor tears. This particular version is quite interesting, as I’ve never seen this style of backing on the dots before — truly unique. Original instructions are not included, but a copy will be provided.
