If you haven't seen the show, the opening credits show the stark black silhouette of a suited man falling through the air. Behind him are buildings that show ads of the era (the show takes place in the 1960s). This opening sequence has been spoofed many times, including by the Simpsons.
Anyway, the shoes I made have the same silhouette hanging on to the falling blinds, while his briefcase and his hat drop beneath him. I'm just glad the customer loved the shoes, and so did the guy she was giving them to! ;)
