TIZ

People who are forced to stand on their feet all day know what sore, tender, perspiring, burning feet mean. They use TIZ, and TIZ cures their feet right off. It keeps feet in perfect condition. TIZ is the only remedy in the world that draws out all the poisonous exudations which puff up the feet and cause tender, sore, tired, aching feet. It instantly stops the pain in corns, hard skin, and bunions. It's fine for chilblains. Ah! how comfortable your feet feel after using TIZ. You'll never limp or draw up your face in pain. Your shoes won't tighten and hurt your feet.

Get a 1/1½ box of TIZ now from your chemist's or stores. Just think! a whole year's foot comfort for only 1/1½.
(Lancashire Daily Post, 8 January 1917)

Does 1/1½ mean one shilling and a penny ha'penny?

Almost exactly the same advertisement appeared in the Los Angeles Herald, but the cost was 25 cents. cdnc.ucr.edu/cgi-bin/cdnc?a=d&d=LAH19180307.2.668.3
