Maybe we can change that, ' " Maravilla said in a video he and his friends uploaded on YouTube, explaining how they went about accomplishing the daring feat.
Their plan involved purchasing a McDonald's golf shirt at a thrift store for US$5.99.
"I noticed there was a blank wall at McDonald's so I decided to make this fake poster of me and my friend".
Twenty-one-year-old Jehv Maravilla and his friend Christian Toledo hung the poster at one of the fast food chain's branches in Texas.
Amazingly, they arrived in the restaurant, put the poster up and left without any real McDonald's staff member coming to question them.
Brynn Shuller of Burbank, Calif., tweeted that she and her friends slipped photos of themselves into picture frames for sale at a Walmart.
Jevh sought help from friends to finally hang the poster up.
"It fit me perfectly", he said. One of them even dressed up as a store employee instructing his pals to put up the poster, which hasn't been removed since July 13. "We didn't want to vandalise the restaurant", Jevh told the BBC.
"We all deserve equality and all races deserve recognition".
They found a "natural environment" that looked similar to the locations used for the existing photos, and took a picture similar to the ones they had seen inside the restaurant.
In a statement obtained by DailyMail.com, Pearland McDonald's franchisee Mariselle Quijano said, "We take pride in highlighting diversity in every aspect of our restaurants".
The pair have shared pictures on social media of them posing as McDonald's models, which has been shared more than 900,000 times.
What the future holds for the poster is a question only McDonald's can answer.
"To this day, I can say that the poster has been up since", concludes Maravilla, "and I really hope they never take it down".
