This antique encyclopedia page includes a definition for the word “BALLOON”. An illustration of a hot air balloon is included. 
I’ve scanned the following page as well, which includes the remainder of the lengthy definition for balloon. 
Here is a black and white clip art version of the balloon.

I scanned the original pages from The Teachers’ and Pupils’ Cyclopaedia, 1905.
