A rare book fair with cool treasures is coming to D.C.

The intrigue: Founders Eve and Edward Lemon are a 30-something-year-old D.C. couple — so not the stereotypical demographic for rare books, though they're both avid collectors.

• Their first book fair two years ago had more of a soirée vibe with drinks and music to attract a younger clientele.
• "In the digital age, there's increasingly more interest from younger people in the physical items," Edward Lemon tells Axios.

Zoom in: This year's fair features 35 dealers and local shops like Capitol Hill Books, offering everything from early editions to modern sci-fi. A sampling of cool collector's items:

• First edition 1814 "Mansfield Park" by Jane Austen ($40,000)
• First 1908 printing of "Anne of Green Gables" ($40,000)
• First 1861 edition of Charles Dickens' "Great Expectations" ($25,000)
• A prized letter from George Washington ($550,000)

Still, "don't be intimidated," says Lemon. "There's stuff at our fair that costs as much as a D.C. coffee these days."

If you go: The Capital Rare Book Fair kicks off with a party ($50) on Friday and runs through Sunday with speakers and events. Admission is $15, free under 16.
