The feud between the rockers spilled over into the legal arena over a poster created by the Aquarium, promoting a fictional boxing match between "bitter" Billy Childish and Jack "whingy" White, the Independent reported.
White's attorneys had the posters pulled from the eBay Internet auction site and warned Aquarium owner Steven Lowe he was infringing on the White Stripes' intellectual property rights, the newspaper said.
"It was just a bit of fun but these people don't seem to have a sense of humor," Lowe told the Independent. "I've written to the White Stripes' management to see exactly what copyright we're infringing."
The stars' feud began when Childish told a GQ magazine interview he couldn't "listen to Jack's stuff."
White, in turn, accused Childish of being "lonely" with a bad case of "garage rock bitterness."
