A few years ago, I came across the blog of Dan Christensen — an artist with a style that is an odd (but, engaging) mixture of modern sensibilities and nostalgia. He has his own projects, including a cool noir fencing story, but last year he showed true, Marvel badassery with his alphabet of superheroes.
Visit his blog and enjoy yourself. I hope, in years to come, we see more out of him. Much more.
P.S. His Tigra rocks. And, that X-Men…well, Ice Man in boots warms the cockles of my heart.
