These doorknobs were taken from my mother-in-law's home in the Rice University area of Houston when it was torn down. We have 12 complete sets, $20 each,as well as several sets with a glass doorknob on one side and a brass doorknob on the other side, $15 each. We also have several sets with a glass doorknob on one side and a turn lock on the other side, $12 each. The house was built in the late 30's, so these are quality items. Come see for yourself!
