Here in the northern hemisphere, the days are getting brisker and the leaves are changing colors. So for this Throwback Thursday (#TBT), we've put together a slideshow full of fall imagery. Why not sit back, read up on some Coke history, and trade in your pumpkin spice latte for a refreshing Coca-Cola this week?

1937 barbecue ad

"A Great Drink to Eat With!" declares this 1937 ad, featuring an autumn barbecue. We have to agree. In fact, our Food section is chock-full of features on barbecue alone, from recipes for Coke-based barbecue sauce to stories on the passionate debates over barbecuing traditions.

1938 Haddon Sundblom ad

This 1938 painting was created by artist Haddon Sundblom. If that name sounds familiar to you, you're probably well-versed in your Coke lore: Sundblom is perhaps most famous as the creator of the Coca-Cola Santa Claus.

1948 Sprite Boy ad

This 1948 advertisement features Sprite Boy, a character who interestingly enough existed two decades before the introduction of the beverage Sprite.

1951 Take Coke Along ad

This 1951 ad depicts a couple enjoying an outdoor picnic. We believe in simple moments of happiness like this - so much so that we recently transformed a drab city square in Lithuania into a pop-up park full of picnic baskets, kites, frisbees and music.

1956 Friends Forever calendar page

This illustration of a girl and her dog comes from a 1956 Japanese calendar, but the sentiment is universal. We recently featured not one, but two slideshows of reader-submitted photos of their beloved dogs. Stay tuned for our third and final "Paws and Refresh" feature!
