{"product_id":"blue-print-design","title":"BLUE PRINT DESIGN","description":"\u003cp\u003eA blueprint is a reproduction of a technical drawing using a contact print process on light-sensitive sheets. Introduced by Sir John Herschel in 1842, the process allowed rapid, and accurate, production of an unlimited number of copies. It was widely used for over a century for the reproduction of specification drawings used in construction and industry. The blueprint process was characterised by white lines on a blue background, a negative of the original. The process was not able to reproduce color or shades of grey.\u003c\/p\u003e","brand":"HARRY JAMES","offers":[{"title":"Paperback","offer_id":44348196880545,"sku":"9781111142590","price":39.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0462\/1120\/3233\/files\/1kwy2znw-front-shortedge-384.jpg?v=1748619509","url":"https:\/\/bookswholesale.myshopify.com\/products\/blue-print-design","provider":"BooksWholesale","version":"1.0","type":"link"}
