Beer In Ads #717: Bring On The Falstaff

Wednesday’s ad is for Falstaff, from the 1950s, I’m guessing. Showing a well-dressed couple visiting another well-dressed couple with the tagline “When Company Comes … Bring On The Falstaff.” Notice how the glass of beer is already full, but the bottle pouring from above it is also still full. Not sure what’s going to happen as that pour continues to spill?
