Boulder's famous landmark is its Flatirons rock formations. Their geography rises above the town inspiring locals and visitors with their beauty.
Being that I live here, it's the most common thing I get commissioned to illustrate. I've drawn them so many times, I no longer require photo reference. Below are all of the Flatirons I've created professionally over the years. These can be found on travel posters, murals, websites, event posters, comics, food packaging, and t-shirts. Most are in my common poster style but I've also experimented with different aesthetics.
Many of these Flatirons can be found in my Boulder travel posters.
