As seen above, the various art galleries function on their different institutional goals and needs. Even artist selection is a key component of any art gallery when considering which artist will fit into the existing schema of operation. Many people unfamiliar with the concept of an art gallery may simply take it at face value. Most people assume that once they are signed with an art gallery, they automatically adopt a group of customers, ready to buy their work and make a profit. This could not be further from the truth. While most galleries do have a regular customer base of sorts, it is not guaranteed that the existing client base will buy the work.
