The inspiration for this lesson came from a post I seen on Facebook of a couple people dressed up in these gas masks holding money. Instead of putting dollar signs in the eyes, I drew what is supposed to look like a bio-hazard symbol. The long elephant looking filter is made of metal and rubber tubing. In general this should be a pretty simple tut to tackle, I had fun with it so I know you will too. especially those of you that like this type of tattoo art. Learning "how to draw a gas mask tattoo" is going to be one of the more exciting tuts you tackle today.
