I purchased these pants a long time ago on these forums from this thread:

They've really done nothing in my collection but sit in a box and I don't really want to collect a lot of GU memorabilia. I'm hoping to sell them, but not sure the best way given that I don't have a great way to prove authentication other then show where I purchased them.

Anyone have any thoughts?
