Transparency paper

Hey guys,
I'm printing a project on transparency paper. I was just wondering if there was a difference between transparency paper and backlight film paper. Which one of these does Jeff Wall use?
thanks

I have no idea about Jeff Wall, but there are different transparency media. I have (2) Art Supply stores which sell the media by the sheet. It is cheaper to purchase the box for a large projector, but for testing I would buy a sheet for testing.

I use self adhesive media all the time (SA/CLEAR/IJ/A). Just do a Google search and you will find online vendors of all kinds of printing media.
