The 100th episode of the series.
The "used brick" referred to in the title refers to recycled bricks that became very popular as a result of the great Chicago fire of 1871 that destroyed 17,500 buildings. Millions of damaged but serviceable bricks were salvaged and shipped around the country at a very cheap price. A prominent feature is the irregularity of the coloring of the bricks due to melting and smoke and other damage. By the mid-20th century the "Chicago used" style of bricks became so popular that factories would intentionally burn bricks to provide an authentic look. Home listings would include "used brick" as a feature in their descriptions.
