A | MILWAUKEE -- A Milwaukee comic book shop is looking to sell a rare copy of the first appearance of Spider-Man.Collector's Edge has acquired a copy of Amazing Fantasy No. 15, the Journal Sentinel reported. The comic book, written by Marvel Comics icon Stan Lee and published in 1962, tells the story of how Peter Parker was bitten by a radioactive spider, gained amazing powers and learns that with great power comes great responsibility.The shop's owner, Steve Dobrzynski, first posted photos of the book on social media last Tuesday. He told the Journal Sentinel a couple found the book among a dead relative's possessions and brought it to him for help selling it. He did not name the couple.A near-perfect copy of Amazing Fantasy No. 15 sold for $3.6 million at auction in Texas in 2021. The Collector's Edge copy is worn and the edges have small tears.Dobrzynski sent it to the Certified Guaranty Company, a Florida-based comics and collectibles grading service. The service rated the book at 3.0 on a scale of 0.5 to 10, with 0.5 being very bad condition and 10 being perfect condition. Dobrzynski said the book could fetch as much as $35,000.“It depends, if you put it up at auction, who's bidding on it,” he said. “If nobody's bidding on it, it's obviously going to sell for a bit less.”Dobrzynski contacted some regular customers to give them a shot at buying the book before making it public, but he hasn't gotten a yes or no from any of them yet.“They’re thinking about it, but I can only wait so long for people to think about it,” Dobrzynski said. “If I’m selling it for someone else, my due diligence is to try to get the best possible price I can.”。 中新社北京8月25日电 (记者 刘亮)中国国家市场监管总局25日公布,由中国专家牵头制定的国际标准《电子和通信设备用变压器、电感器的测量方法和试验程序》,由国际电工委员会(IEC)与电气电子工程师学会(IEEE)近日联合发布,正式成为全球电子通信磁性元件检测领域统一技术规范。 国家市场监管总局介绍,该标准的发布标志着中国在该领域正式跻身全球标准引领行列,为5G通信、算力基建、新能源汽车等新一代信息技术与新能源产业高质量发展,筑牢了底层标准根基。 据介绍,该标准精准适配5G和AI(人工智能)服务器电源、新能源功率变换等前沿产业发展需求,统一规定动态电容、热电偶温升、增量电感、差分电感、能量电感、振幅电感测量等关键测试方法,以及高频工况损耗、交流电阻等十余项试验流程,为全球磁性元件的研发设计、性能检测、质量评定提供了统一、权威的国际技术标尺。 此前IEC、IEEE两套标准技术要求存在差异,检测结果难以互认,企业出口面临重复检测、多重认证,对国际贸易形成实质性技术壁垒。此次发布的标准实现欧亚、北美两大主流技术体系融合互认,建立全球统一测试基准,有助于降低全球企业重复测试与合规成本,打通磁性元件全球供应链技术壁垒。
