I notice that almost all magicians use Bicycle brand to make their gimmicks, for example Shim Lim's Flash Deck Switch 2.0. What are the copy right rules of having Bicycle brand logo on made gimmicks? Do I have to get permission or what guidelines do I have to follow for making a gimmick and have Bicycle brand name on my product?

I am only using the front of the box image for my gimmick, and selling it as a gimmick and not a Bicycle product, even though it will have the Bicycle name and logo.

I have searched everywhere trying to find this answer, any help will be great!

As long as you use the product that bicycle sells to make the gimmick you will be fine. If you need to re print an image they own you now may have a problem. You can cut any product up and make anything you want as long as it came from the direct source. I.E. you can make a trick out of a Coke bottle but you can not make a bottle that needs a label not made by them. that's my understanding and not to brag, but I am not an attorney.

A good example is that it is legal to buy 52 decks of bicycle cards and re-sort them into one-way forcing decks and to sell them as forcing decks for a profit.
It is not legal to print cards or boxes using the bicycle images.

Thank you for the feedback! This does help in understanding the copyright issues.
