Anyone Else Like Beer Memorabilia?

Picked up these three at an auction for $22 for the lot. I couldn't make it to the auction dad was going to the sale anyway so I asked him to bid on some framed print advertising that was hanging in the shop. He didn't see them so he bought me these instead. It was the estate of a friend, his shop was the local hangout. So it has a special meaning to me.
They need some cleaning, anybody have some does and don't on cleaning them? Any sights that has tips?
