Lincoln Logs��a set of log-like building pieces�?eached the American market in 1920. Designed by John Lloyd Wright, son of the famous architect, the sets built log cabins, frontier forts, and other structures. In the 1920s, some Americans viewed the log cabin as a symbol of the frontier spirit and democracy (a number of 19th-century U.S. presidents�?ike Abraham Lincoln�?ad rose from humble log cabins beginnings). Toys promoting these virtues appealed to parents concerned about raising children in an increasingly industrialized and urbanized America.
