Vintage 3" tall illustrated header bag contains the magic cube with instructions on the reverse.  The net effect is that the performer can know what color cube is in the box making it appear that the cube changes colors. These have a great header with a magician pictured. They are from around the 1960s and are in excellent condition, although you might see some slight rust on the staples if you look really closely. Colors vary.

 

You might remember that about a month or so ago I headed down to my favorite toy store in Kentucky and brought back a bunch of items that appeared in the catalog a few weeks ago.  I went back two weeks ago because as I was leaving last time, I noticed an area in the basement that I had never been in (the basement of this place is huge).  I had to see what was there, and it turned out there was a lot of items that had not seen the light of day for years.  So, this is part of that haul. At one time they had a live magician in the store and so they sold small magic novelties like this back in the day.
