This book focuses on sports related facts, events and trends that are not typically highlighted.  For example, how uniforms and sports-related fashion have evolved over the years, how ancient sporting events relate to modern ones, the effects of technological developments and how sports equipment has changed.  The pages are really packed with text boxes, colorful backgrounds, graphics and photographs, I fear to the distraction of some readers.  This is a fun book to pick up again and again, even just for a short time to read one section.  The text is clearly written and thematically organized.
