McDonald's has been celebrating the 50th anniversary of the Big Mac all year, and the work just keeps on coming.

A number of ads by TBWA offices around the world have emphasized how the burger has stayed the same throughout the changing looks and styles of the decades, including a set of posters that contrast 2018 with previous years like 1968.  The latest work, from TBWA/Paris, is a print and digital campaign that takes a funny look at what the McDonald's customer themselves looked like in the '60s, '70s, '80s and '90s --think beehives, golfing sweaters, big hair and shoulder pads, stonewashed jeans and more.

As well as the posters, there's a fun digital element: with interactive Facebook and Snapchat filters that allow participants to take a step back in time as well by asking them what they looked like during the different decades.
