12mo - 18.5 x 12.5 cm.; 192 pp. Red cloth over thin though rigid boards with black lettering. Number 4 in the "Second Thoughts Library". Illustrated with small black and white drawings. The externals show only mild shelf wear though the spine is a tad faded. The end papers are browned with a previous owner's stamp residing on the front free end paper. The head margins of the text paper show the same age toning or browning but much less so. All in all, a clean and solid little volume.
