I bought 2 boxes of miscellaneous magic at an auction last summer and I am just getting around to looking at it.
One of them is the "Boomerang Card Change"
It included the instructions & gimmick but unfortunately I broke the gimmick when I was examining it. I was too impatient.
I have the elastic thread needed in my toolkit but I don't know how to install it through the cards' holes.
If someone could tell me or provide a photo of what it is supposed to look like, I would be grateful.
Otherwise, I'll just toss it.

Please PM if this is exposure.
Thanks,
