Just got a significant baseball cardboard advertising piece that was rained on and the water soaked through the usps box before I got home. Regular postal lady always stands packages up close to the door or behind a chair. This was just placed flat in front of door and subsequently took a hit of rain. Bottom 3-4 inches of the piece itself soaked up some water with discoloration already setting in. This is a piece I'm absolutely sending in for restoration so do I just let them deal with the water issue then or is there anything I can do right now to lessen the damage. It's currently still wet!
