Clare, John D., ed. Food and Feasts in the Middle Ages. New Discovery Books, 1994. Photos of period illustrations. Looks quite good with background in agriculture and culture.
Error rate varies among titles but is uniformly low.
Costume information ditto. Life in the Renaissance. Random House, 1968. Uses only period illustrations in black and white, halftones, and full colours. A good basic overview of knighthood in the Middle Ages.
