Amy and Steve tried to preserve the old gas station as much as they could (there was even talk of an Otis Hill Burger).  The original Humble Oil restroom signs were saved and installed in the restrooms (in a language of service and detail that is practically lost today):  The management of this service station inspects this restroom regularly and strives to keep it clean at all times.  If it needs attention, you will do the next user a favor by tripping this switch.  Prompt attention will follow.  Thank you, Humble Oil Refinery Co."

Their painter and concrete artist formed bricks where the old ones had chipped away.  The garage doors were carefully repaired; the original casement windows were filled with colorful glass.  Made in Common Fort Guanajuato, each concrete tile was made by hand, the colors dipped into the wet concrete and swirled in one's chosen pattern.  During the French occupation of Mexico in the mid 1800s the French installed this style of concrete tile in government buildings and palaces.  The Mexican people mastered the art of the tile and became better at its manufacture than the French, adding colors and intricate designs.  Still commonly used in Mexico, this tile is rarely transported to the U.S. due to its weight.  Luckily, "Phil's Tiles" were able to piggyback their way to Austin with a load of merchandise destine for El Interior.
