A printing technique that involves carving text in relief upon a wooden block. When inked, the impression is transferred to paper. The oldest known printed works were produced by this method in Japan and China during the 8th and 9th centuries. This method of wood-block printing appeared in Europe in the 14th century and eventually inspired Johannes Gutenberg to create type pieces out of metal.
I really like the frame. It's sturdy and well made. In the one I've opened, there's a little imperfection in the glass that's not noticeable if it's set at the bottom (horizontal) side of the frame. It showed a plot more at the top.The mat is off white. I was expecting white. I can still use it, though. For the price, it can't be beat.
