20th Century Invention

Thanks again to Laurie54 for hosting monomonday this month. This week is the 20th Century.
And my choice for today is the tea bag. 1908 by Thomas Sullivan apparently.
This is a herbal tea - peppermint, my go to choice when I want a hot drink but don’t fancy tea. I try not to have too much milk these days, and the peppermint tea is very gentle on the digestive system.
