88x31 pixels was a very popular web badge/button image size in the 1990s, especially among freewheeling and independent sites created on services like GeoCities, and there are IndieWeb 88x31 badges you may use.

Welcome to the 88x31 archive on hellnet.work! This site contains 31,119 unique* 88x31 buttons that I scraped from the GeoCities archives compiled by the incredible ARCHIVE TEAM before GeoCities' demise in late 2009.
