This listing is for a very nice:  Chicago Field Museum Program PAUL G. DALLWIG, THE LAYMAN LECTURER

The condition is very nice showing minimal signs of age

It is from 1940

It measures approximately 5 3/8" x 8 1/4" with 3 double sided pages

Mr. Dallwig describes himself as "a lawyer by profession, a businessman by accident, and a scientist by remote control." He used to sell insurance but has given that up almost entirely, still makes money from a special loose-leaf notebook which he invented for insurance salesmen. One day in 1935, oppressed by business cares and seeking distraction, he dropped into the museum, listened to a stock lecturer. When it was over he found that his cares had fallen away. He went to about 100 more lectures, began to bone up on geology, anthropology, mineralogy, meteoritics, zoology, paleontology.
