As Musk remakes the company formally known as Twitter in his own image, mementos of the platform's past life are moving on.

The company is auctioning off art, furniture, and other bird-brained oddities from its Santa Monica and San Francisco offices. The auction, diplomatically named the "Twitter Rebranding," opens on Sep. 12 and the most unique pieces could go for tens of thousands of dollars.

Earlier this year, memorabilia of the blue bird mascot (named Larry) sold for upwards of $20,000 at an auction put on by the same auctioneer.

Scrolling through the listings — which include guitars, phone booths, work tables, sofas and more in addition to the more unique fare — it's hard not to feel a tinge of melancholy for the big ol' bird-shaped brand.

But I guess nostalgia and reverence are a low priority when you're out about $30 billion.

Here are some of the coolest pieces up for grabs.

This statement piece comes with a built-in charging port and outlet, but that's where its practicality ends. It's more than 67 inches long and its half a dozen pointy edges are literally a design feature.

Imagine getting up for a drink of water in the middle of the night and bumping right into the beak. It'd be an iconic statement piece for a home, but at what cost?

These oil paintings by Debbie Fass commemorate two of the platform's most viral posts. Ellen Degeneres's star-studded selfie, taken at the 2014 Academy Awards, became the most-retweeted photo of all time within an hour of being published.

After winning the 2012 Presidential election, Barack Obama's tweeted this photos and the words "Four more years." It was the most-liked tweet in the history of the platform at the time.

This nearly five-foot-tall bird likely hung in the halls of Twitter's Boulder, Colorado office before the company was evicted for not paying rent in June. It features Coors Field and other local landmarks in a vibrant collage.

Buy these to become a bird in your own personal gilded cage. The gold swing features an open design, but you can close the door and lock yourself into the black cage which comes complete with a little bowl of resin designed to look like water.

This 34-foot-long sign celebrates Twitter's longtime tweet prompt "What's happening?" (now a more chaotic "What is happening!?") with a sly eyes emoji. From one side, only the slogan is visible and, from the other, only the emoji.

It's an enormous piece, standing almost six feet tall. Maybe Musk just didn't like the idea of being watched.
