Vintage 25 Magic Tricks Kit Unopened Original Packaging 1970s Made for Reiss Games out of New York, New York, and Orange, California by Show-Biz Services out of Brooklyn, New York.

10" x 6" ~ Package size

Such a neat find. These are from 1976 and 1977 the only difference I can see is the color of the magician's secret packet is white on the front in the 1976 version. I have not opened any to verify as I don't want to ruin one. 

Reiss Games seems to have not survived to the present but Show-Biz Services is alive and still supplying young David Copperfields to this day.
