The sky: spring and summer nights
A short star-identification guide by Dorothy Louise Brown, published in 1920 by the Woman's Press in New York for camp leaders and amateur observers learning the seasonal constellations. The nine plates are white dots and connecting lines on grainy black grounds, labelled in light sans-serif type: reusable diagrams of Leo, Scorpio, Hercules, Boötes and Pegasus with named stars.
