One of many online galleries is MyBestCanvas.com - Art forum & artists community offering oil paintings signed by painters from USA & Europe. Just looking at the collections would be a relaxing escape in the middle of your routine activities at the office. And maybe you will find a piece of work of art there that goes with the ambiance of your living room.
I found this simple yet beautiful painting on the site, titling "Old is Gold" (2006,Mixed Media on Canvas , 50x25cm), painted by Sarika Soman, a female artist who was born in the vibrant and colorful country of India. Her works have been exhibited in U.S, Germany and India.
