FAIR WARNING: the above-linked video takes about nine seconds to get going ...be patient! D:
Anyway, I drew Woodlore with my Wallace Zephyr pencil and delineated him via this WWII-era 'Evergreen' pencil from US Pencil Co. The Evergreen is a very VERY good pencil! I'm lucky enough to have several stubs of this pencil to play with (I will be using it again). The Evergreen's line is thin, its drag is smooth, and it erases ...fairly well, though given the thinness of the line, the 'nib' does tend to create grooves if one isn't careful. This pencil was sharpened to a high point, but as it wears, it'll get better. :3
I love "In the Bag", the Disney short cartoon, where Humphrey ends up having to clean all of Yellowstone park. Smokey Bear even makes an appearance. It's the film where the "bump-bump" comes from. There's currently a complete copy on YouTube, but it's all worn and faded. https://www.youtube.com/watch?v=E_yYmnc7f78
