Primary Market: is one who works with direct artworks from the artist. Example, own visual artist, the gallery that represents, etc.
Secondary Market: is who sells works who have left galleries of the primary market, or who saves them. The secondary market is when a work of art has been marketed more than once.
Why Artyou makes the difference Primary Markets and Secondary?
The Artyou has numerous marketing activities, and to better target information stores and searches, Artyou separates the two markets to better serve customers.
