MAMA Director Jacqui Hemsley welcomed the generous philanthropic donation and said "The Joss Family Galleries" would be home to MAMA's prized permanent collection.
"It's very apt that the Joss family, who are so committed to our community and such a part of the history of Albury, are now a major benefactor of MAMA," she said. "The two galleries named in their honour will house MAMA's permanent collection and will for ever be known as The Joss Family Galleries."
Ms Hemsley said the permanent collection was "a jewel of MAMA" and included more than 2400 paintings, works on paper, sculptures and paintings by leading 20th Century Australian painters including one-time Albury resident Russell Drysdale, Donald Friend, Charles Blackman, Mike Parr and Fred Williams.
The Joss Family Galleries will also present exhibitions from the extensive photographic collection of more than 600 pieces, including works by well-known photographers Max Dupain, Rosemary Laing and Tracey Moffatt.
"The old gallery did not have the room the feature the collection like this new building can," Ms Hemsley said.
