This one page, one sided flyer advertises two different The Scarlet Letter formats which were published in 1892. Thus, I believe this flyer was printed in 1892 also.
The book pictured on the flyer has an identical format to an 1891 Addresses by Drummond book. It is unclear whether these books belong in a series.
This little flyer is 6″ x 3.5″.
