All Museum Donation rewards in My Time At Portia

You can donate Relics, Artwork, and Fish to the Museum in My Time at Portia to get unique rewards that you won't be able to get anywhere else in the game. In order to donate items, go to the Museum and talk with Merlin, and interact with open places where you can place the items you want to donate.

Each item can only be donated once, so it's actually a bit difficult to get the rewards that require the most items donated.
