Throwback jerseys and design are all the rage. The Bears do it, the Cubs do it. Heck, even Pepsi and Burger King get all nostalgic with retro packaging. Yesterday, the CTA spruced up its aging 2400 Series trains for a final trip around the 'El' tracks. Transit Authority employees wore vintage uniforms, replete with those nifty coin dispensers that people over 40 will recognize (and I guess dudes in Brooklyn use them as wallets today?). The train cars were bedecked in Bicentennial flair, with patriotic blue and red stripes and "Spirit of Chicago" signage. Even the advertising inside was era appropriate, including a promotion for Dick & Doug morning show on WCFL AM 1000. No, the smoking ban was not lifted. Pop in a Styx eight-track and flip through these cool pictures of the event that we found on Instagram.
