 The pictorial images are centered on two pivotal linchpins: a traditional lighthouse and a navigation satellite. The lighthouse is the most prominent of all T-M forms. Lighthouses have been photographed, painted, have appeared on countless calendars, have been the focus of preservation efforts (and in inverse proportion to their practical significance). Lighthouses bespeak of a previous era and can serve as a reminder of all traditional safety aids. The navigation satellite presents a new safety aid, that of GPS, and represents a form of safety aid of ever increasing importance. The remaining images are grouped around these key elements.
