Dysphagin Tutocain Local Anesthetic Pill Container

Original Dysphagin anesthetic pill container. The side is marked D.R.Wz. (stands for 'Deutsches Reichs Waren Zeichen' whichis a registered trade mark).The tablets that this originally contained would have been dissolved in water then heated to sterilize it and injected as a local anesthetic. It measures about 2 3/4' by 1 3/4'. The tin is in decent condition and does show some wear.
