However, Bob's look is inspired by men's makeup from the Art Deco era, especially the 1930s. The stars of the silver screen were not averse to wearing big, bold, goopy levels of mascara that went beyond simple stage makeup and into the realm of fashion statements. Here are some examples:

James Cagney (known for rocking fair hair and dark mascara)
Makeup trends also influenced Golden era illustrators like Kaye Nielsen, J.C. Leyendecker, and one of my favorites, John E. Sheridan. Sheridan often gave his young men a dramatic look, like the one below.

Thus, Bob's eyelashes tie in with his wingtip shoes, plus fours and trench coats. They are retro and quirky, and fun to draw. And of course, they match his llama's.
