This is an original photolithograph by Jim Bird, paying tribute to Vasarely in 1972. The artist has signed this piece and it comes framed and matted. The size of the artwork is medium and it is an excellent addition to any art collection. The style of the piece is similar to that of Vasarely, making it a great conversation starter. It is an original piece, not a licensed reproduction. It measures 27.5 by 27.5. It is signed in pencil and numbered 73/75.
