The Rusty Mammoth
Curate your home on a budget and support the Moses Lake Museum & Art Center.
Shop the museum’s annual summer Benefit Art & Collectible Sale, and find select items in the Museum Store year round. Thanks to our generous donors we are able to take what one person no longer needs or wants and turn it into someone else's incredible treasure or bargain.
Donors to the program can take pride in knowing that their once beloved treasures will go to a new home, and benefit museum's educational programs, collections and exhibits.
We are happy to accept donations year round. Gently used good quality items are always welcomed and appreciated. We prefer items that fit into these categories: Art, Collectibles, Antiques, Ceramics, Glassware, Books, Art Supplies, Textiles, Home Decor, and Jewelry.
