As always Angus McBride's color plates are as lifelike as can be. Especially, plates A,E,F, & G. These elite series are more in depth than the usual armor, weapons, & uniforms. The text is more varied. From their origins in the eigth century to all their adventures from all compass points, we get little gems of information. A refreshingly wide range of sources are used. Norse sagas, English, Arab, Byzantine, Frankish, & Irish chronicles. Most areas are touched on to varying degrees. From their tactics, well known campaigns, & the Varangian guard to the less known "Jomsvikings." The latter being independent, strictly run mercenary companies.
Also, some interesting anecdotes: Did you know that dark hair was much more common among the Danes than the Swedes & Norwegians? That certainly would explain the physical appearance of the Normans on the Bayeux Tapestry. If it had a dozen more pages I would have given it five stars. For 63 pages it was well worth the price.
