This is a very attractive deck. Thank you for sharing it with us on this site.
You make mention of Love Scenes as being the fifth in a series of 8 issued by Mortimer Nelson, therefore, I am taking the liberty of posting a photo of a partial wrapper from another of his decks that clearly indicates what the subjects of these 8 decks are and confirming that, indeed, your deck is the fifth in this series. It may be nearly impossible to see in the photo, and it is even hard to see on the wrapper itself, but the middle section of the wrapper between the portrait of General Polk on the left panel and the verbiage on the right panel reads "Picture Playing Cards". The small print at the bottom of the right panel states "Entered, according to Act of Congress, in the year 1863, by M. Nelson, in the Clerk's Office of the District Court of the United States for the Southern District of N. York."
