This cartoon describes the heliospheric consequences of one of the Sun's most memorable flares, namely the prototype coronal hard X-ray source of March 30, 1969. The flare, inferred CME, and consequences were well-observed by many modern-sounding facilities even in spite of its occurrence in a dimly remembered bygone era - almost four decades ago! These facilities included hard X-rays from OSO-5, the Culgoora long-wavelength radioheliograph, a microwave imager in Japan, and as many as six independent platforms for cosmic-ray observation scattered loosely about the heliosphere. Note that this excellent array of instruments led to a cartoon featuring a blast-wave disturbance in the outer corona, rather than a CME-driven shock. This is a topical matter even today, and these authors probably saw things more clearly than many latter-day pundits.
