Archival Footprints™ is the name given to these glass tiles because the text on the tiles is taken from personal family archives. I have a long time fascination with text. This text is readable only in places, to convey fleetng glimpses of a mood, a feeling. Each tile is 4" x 4" by 3/8" and is made of 100 percent recycled glass. Each tile is unique. Appearance will vary, even within the same series.
