This is the first in a series of gas mask themed illustrations and designs I’ve been working on. Gas masks, gas masks, gas masks! I know gas masks are over-used in a lot of post-modern artwork, but gas masks (gas masks) are so much fun to design! Guilty-pleasure (gas masks). In case you were wondering why I’ve said gas masks so much in this post, according to SEO (search engine optimization) the more you use a certain keyword, like gas mask, the more likely your image will be ranked in the first 10 – 100 images on Google. So, gas mask on, everyone!
