One book you should definitely have in your collection is a retrospective of Americana. The SFMOMA published an outstanding book covering the works of Jasper Johns. Seeing with the Mind’s Eye is a collection of Johns’ works over his career.
The book contains his paintings, prints, and sculptures. Seeing with the Mind’s Eye also coincides with Johns’ exhibition at the SFMOMA which was held from November 2012 to February 2013.
I believe this should be in your collection because of the craftwork and ingenuity Johns’ body of work contained. Also, if you missed this exhibition, this is a wonderful way of immersing yourself in his work even if you did not attend.
