It appears to be a can of a human soda. This looks like the defunct "TAB" soda. You read the bottom text and learn that it's made by Coca Cola. You sort of remember looking at humans with this back in the 70's. Yes, it's all coming back to you.
It started as a human brand, drunk exclusively by the humans of the latter half of the century. Then, after a lot of time had passed, fewer and fewer people drank it, until it was funny to see it in older media. It was eventually discontinued, and the Coca Cola company dumped all their remaining product into the trash. That trash eventually made its way to the underground, and monsters started drinking it. The Monsters began to have this distorted vision of what humans drank, because all they had was the Tab, which they liked.
Once the Monsters left the underground, they were expecting all the humans to be drinking Tab all the time, but were disappointed when they couldn't find a single store selling it, not even the weirder stores that have an extreme variety of products that you would never expect to find anywhere else. So, they started their own factory to make some Tab in Newer Home, and everyone was happy. Except the Coca Cola company, who tried to sue the monsters who only wanted to drink some Tab, but the case turned out that the creators of coca cola actually filed the trademark under "Tqb" which isn't an actual word, so the monsters were fine.
You appearified the cans from the factory itself. You don't know why, but the random numbers you plugged in allowed you to appearify from there. You then took a huge amount of tab and then went to working.
