The company of Ernest Treganowan, Inc. made many of the Girard-designed rugs for the Miller House including the three rugs for the Children’s Playroom (later Mrs. Miller’s Office). These invoices show the increase in price from $1,232.21 in 1955/6 to $3,218.70 in 1972 and $10,336.86 in 1992. Although the rug was produced in slightly different sizes, comparing the rug presently in the house with historical photographs show Girard’s color-block design did not change.
