Ceramic tile with cork backing from the Institute of Scientific Information (ISI) Thomson Scientific in Philadelphia, PA. This 4.25" x 4.25" tile was a Thomson giveaway at the Special Libraries Association (SLA) Annual Meeting. I cannot recall what year this tile was a merch giveaway but it was between 1996 and 2010. Tile is metallic gold and red and branded "ISI Thomson Scientific". In good vintage condition.
