For centuries, canvas has been the most popular and widely-used painting surface for fine art. One of the earliest works on canvas was painted in 1410. Until that time (and for some time after that) artists worked on wood panels. Early canvas was made of linen, but today's canvas is typically made of cotton. Barewalls.com has a large selection of canvas posters which depict a wide range of subjects, including music art, movie art, and Rolling Stone magazine covers. Canvas art is highly sought after and highly collectible. It's a bit more expensive than standard poster fare, but the quality and texture of canvas give a feel of authenticity to any work of art.
