Edgar S. Yergason's 1859 Double Sided Drawing with Boat and Train

I really can't decide which side of this one I like better. This is the third of three by Edgar S. Yergason that I found together, who signed and dated the back off one of them in 1859. A quick search reveals that Yergason went on to fight in the  Civil War, and to become a well known interior designer in Hartford, CT. I think he showed brilliance at a very young age, giving great life to this ship and train both, and especially, I think, the sea!  My photos aren't great but It should be noted that the graphite on these drawings is a bit faint and so they very much reward close looking. 

8 1/8” w x 8 1/4” t. Horizontal fold and toning as evident, with tiny holes down one edge from where it was stitched into a notebook.
