1. As an artist you can not be in all places at one time selling your artwork.
2. Galleries are a place the artist and collector can meet face to face.
3. You will have another party pitching your artwork to museums, businesses and other groups of people.
4. You will receive more online exposure because of your presence on the galleries website.
5. A collector base will be established for you and if you already have one it will expand.
The artist will be receiving these said benefits (and others) in addition to 50% of the sale. So why does the gallery then take such a large commission? Because the gallery will be responsible for the following: insurance, security, utilities, phone bills, equipment, office supplies, packing, furnishings, employees, landscaping, computers, publicity, art fairs, announcements, memberships, advertising, rent and the list goes on. The commission that the gallery is taking helps to offset these costs and if there should be a profit, the gallery owner can now pay themselves.
Now it's your turn. Do you feel galleries should receive a 40-50 percent commission on the artwork they sell?
