For 30 days in 2011, Juan Ortiz gave himself a task: create a new poster every day, each one illustrating a single episode of the original Star Trek series. "I had little sleep during that time," he says. When he was finished, some friends convinced him to reach out to CBS directly. The posters were a hit, and with CBS' blessing, Ortiz ultimately managed to make one for each of the original series' 80 episodes. The results have been collected in a new book called Star Trek: The Art of Juan Ortiz, which for the artist is something of a love letter to the show. "The original series is ingrained in my head," he explains.

The designs feature a vintage style, with some reminiscent of classic movie posters and others harking back to the covers of pulp sci-fi novels. According to Ortiz, what makes them work — and fun to work on — is the sheer diversity of the episodes he illustrated. "Each episode is its own story," he says. "A court drama, a monster flick, a love story, a war story, a western, etc. So it was easy to approach each episode on its own merits and not be bored with the same idea throughout. I was also my own art director, so I had the freedom to create images of just about anything that I wanted, unhindered by the series' low budget — like dragons on Vulcan."
