Sketchbook Project: Dirigibles

I opted for using the lesser definition of dirigible as 'something that is capable of being steered,' so the whole thing won't be all zephyrs & subs. I thought I'd recreate a few vintage newspaper and magazine articles from the late 1800s, early 1900s to intersperse throughout the sketchbook.  I'm thinking it will end up having a vintage inventor/adventurer scrap-book sort of theme.  I will probably scrawl notes in the margins, draw in some yellowing scotch tape, etc. 

Work in progress #1:

One Man Helicopter. Pencil, marker, pen & Ink.
