CBOT visitors card from 1883, 1884 and 1894

Scaned are the front and back of CBOT visitor cards issued to an agent first of the Chicago and Alton (C&A) Railroad and then with the Illinois Central Railroad. On the reverse of the first two you can see the post-Chicago fire CBOT residence which was in the Chamber of Commerce building and then on the front of the 1894 ticket you can see the subsequent CBOT building. The first two tickets are signed by Charles Randolph who was a CBOT executive dating back to 1863 and was President in 1865. Randolph was eventually made CBOT Secretary from 1869 until 1884 when it was handed over to George Stone whose signature is printed on the third card.
