Replying to How can I use copyright infringement and trademarked work?

Yo so I am in charge of making a logo to paint on the gym wall of my school. I really like the MSU bear mascot, and would like to use it. I know nothing about copyright/trademark stuff so if you guys could direct me in how to do this without getting sued.

BTW, we will project it onto a wall, outline in pencil, and then paint over afterward. How much do I have to change it so it's not the same thing? Will the slight differences in how we paint it be enough to cover it if they somehow find out and decide to sue us (we are in NY and are a very tiny school so I doubt they will).

Also, does it matter that we aren't using it to make a profit and are technically a non-profit organization? Thanks guys! 10k+ for all who answer
