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.
A treasure trove of really neat Internet stuff.
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.
