Personally, it would be awesome for jibij to display them in the store. Having signed items and memorabilia would definitely add a lot of character to the store.
Look at places like Hard Rock Cafe. A lot of times its a lot of fun to just see of of the interesting stuff on the wall. Might be a little cheesy but pretty cool. Maybe start a small freeskiing hall of fame in the store. Considering they are really one of the few newschool specific stores if not the only. And they really have a big impact on the industry.
Example: Having tanner's poles that he used when he won slopestyle at winter X in 04'.
And I doubt they will get $1000 for them. But hey idk, if i could get a lot of money for them I would sell them.
