Type of Work
Vinol was a tincture sold in the early 20th century that promised to cure all kinds of ailments. One cover of this promotional booklet claims it will soothe a woman's nerves and increase a man's pep. In a few words it promises to address both masculinity and so-called "female problems."
The other side calls constipation to the forefront.
Not a great deal of information is online, but it looks to be a sort of snake oil.
Booklet is very small.
