Besides laxatives, cough drops, pastilles, lozenges, and  dragees  are the next most common old tins; I guess they had a lot of problems at both ends back then (not much has changed...Halls, Metamucil, etc.).        

These are all 3 1/2” by 3” and made by the Simpkins Company. These are from around 1940-1945 and the company logo is a  Maltese Cross which was used extensively by Hitler’s Nazi party but did not appear to pick up the same stigma as the swastika.  

It appears that putting pine tar in cough drops was all the rage for a while. I think these tins are from around 1905—1925. Note that the “Peps” state that theirs are a unique and indispensable family “medicine.”  Walpines gives you “the breath of the pine forest” I’m not sure how attractive that would be.

Two very rare and desirable cough drop tins from 1900 or so. I like the use of the word “innocent” to show no opium-like drugs are contained & they were the “greatest cough drop on earth”.

Four rare tins that tend to fetch good prices. The one to the upper left contained pastilles that contained diamorphine (which is heroin) and cocaine; the middle, heroin pastilles, and the other 2, cocaine and other stuff. These are all from England where you could buy or mail-order them from drug stores like Rexall. I think they must be from around 1905-1915.

The three known Nipits tins; one from America and two from Britain. No information available on this company but an educated guess would be that they are from around 1920-1940. 

There is no record of Weaver & Sons ltd. anywhere to be found. These tins are 3” x 2” from around 1910 to 1920 or so.

A tin of  cough drops containing  opium. I cannot figure out what the illustration has to with cough drops. It looks like a weasel in a trap and a dead rabbit with someone else dying over to the left along with  someone seemingly pretty upset over the whole thing (?).
