Correction appended, April 17, 2015

It was 60 years ago this week, on April 15, 1955, that Ray Kroc opened his first McDonald's franchise, in Des Plaines, Ill. It wasn't the first McDonald's restaurant (two brothers actually named McDonald had started the California-based company) but it was the first step on the road to chain-restaurant domination.

As McDonald's enters its seventh decade, here's a look back at images and advertisements from its first few decades — including two, numbers one and three in the slideshow above, which have never before been published outside the company. The company has changed over the years, going international, transitioning from a hamburger joint to a company that sells bed linens, making news with labor issues and breakfast menus alike. But not everything has changed: look closely at the photos of the earliest locations and you'll notice the telltale golden arches.

Correction: The original version of this article mistakenly identified the Des Plaines, Ill., McDonald's as the company's first franchise location. It was Ray Kroc's first franchise location.

The ordering lingo for this Atlanta staple, which debuted in 1928, is almost as delicious as the burger itself: you get it “all the way” in lieu of “with onions,” and “walk a steak” replaces “to-go.” These branding gimmicks were later replicated by burger chains like In-N-Out, whose secret menu (see: “animal style” and "protein style") has helped lure millions of customers.

In October, Chicago heavy-metal-themed bar Kuma's Corner launched one of the most outrageous burgers to date: the Ghost Burger—it's named after Swedish metal band Ghost B.C.—was topped with an unconsecrated Communion wafer. The dish sold well, but angered Catholics (and garnered national headlines), prompting the owners to donate $1,500 to Catholic Charities of the Archdiocese of Chicago.

Although this twist on the cheeseburger—in which the cheese is melted inside the patty—was reportedly invented in the 1920s, when chefs were still experimenting with the burger, it gained national attention in 2008, thanks to a feud between two Minneapolis bars that both claim to have "invented" it. Since then, there have been numerous imitators, proving that a little innovation and a dash of hype is all it takes to reinvigorate enthusiasm for a classic. Correction: The original version of this story misstated the date of invention of the Jucy Lucy. It was put on the menu at Matt's in 1954.
