The bulk of art falls into one of these categories:
Art galleries provide a visual representation of a culture's past. The art in specific works may be more realistic; yet, the artwork in others may be more symbolic in nature.
The promotion of art and artists is another goal of art galleries. Galleries serve a variety of responsibilities, both visible and unseen, such as going above and beyond the standard work of putting up exhibitions and selling artwork.
Today's art galleries make a concerted effort to promote and advertise their artists and current shows. To publicize the works, they issue forth press releases and host relevant events. A budding artist's public reputation and exposure can skyrocket with sponsorship from art galleries.
