Antique German White Block iridescent canister & mini canister sets

28 piece total (including lids). Old sets of White Block canisters, made in Germany. All in very good vintage condition, but Flour canister has a small crack on the inside (see photo). Large canister set is 14 pieces. 4 pc oil & vinegar set & 10 pc mini canister spice set. They are iridescent, which is much prettier in person!
