Hello World: A Life in Ham Radio was made by Danny Gregory and Paul Sahre. It is beautiful, well put together, and educational. The book follows the Ham career of Jerry Powell. The readers find out about Powell and his adventures mostly through his collection of QSL cards, which are the calling card of ham operators around the world. The book was released by Princeton Architectural Press in 2003. It has 256 interior color pages, a spot varnish on the cover, and a rainbow gradation behind a ham glossary on the inside front cover.
