Op Art was the first Fine Art movement I ever engaged with, way back in my early to mid teens. I found a book about it in the school library. Its geometrical aesthetic appealed to me very strongly, so much so that I even made a few pencil drawings of my own that fitted in the genre - I might even still have them somewhere. So when a local art gallery held an Op Art retrospective (I think Brits only) I dashed along to see if I still liked that kind of thing. - Yep! Still love it - bought every book they stocked about it. This is one of them. It's an exhibition catalogue, with an interview with Bridget Riley and a short biography of her, focusing almost exclusively on her artistic accomplishments. The art is fab, given as much space as the middling sized format (for an art book) allows and carefully reproduced to preserve the colour effects of the original.
