1830- 1878 Advertising using indigenous imagery
I believe you can tell a lot about society by their advertising. Even today, ads are directed towards targeted markets and it's meant to entice the public to spend their hard-earned money, buying into a product or service or experience - often times - just through the advertising.
Here, from the 1830's until the end of the 1880's, you will notice that specific products are marketed towards the non-Native audience, and what they are selling are:
Medical Remedies mostly, and then towards the end of the time period, Tobacco.
This plays into the stereotypes of Native people being mystical medicine men with cure-all's, and then to their connection to the peace pipe, and of course the actual tobacco, which was introduced to Europeans by Native people.
