Check out Printlover for some interesting retro and abstract art on eBay, which includes the Don Kunkel abstract silkscreen print above.
Proving oncer again that you can buy some interesting art for next to nothing on eBay if you shop around, this would look pretty cool in a '70s-inspired interior – and would brighten up any room.
Not just a poster, this is a signed print by a known artist, dated to 1970 and signed by the artist in an edition of just 50. It is sized around 68 x 60cm and is said to be in excellent condition for its age. It is also at £4.99.
