According to PANews, the iconic bluebird sign that once adorned Twitter's San Francisco headquarters has been sold at auction for approximately $35,000. The sale was reported by Boston's RR Auction House. The sign was removed following Elon Musk's acquisition of the social media platform and its subsequent rebranding to 'X.' As a central element of Twitter's brand identity since its inception, the bluebird logo has garnered significant interest in the tech collectibles market.
