neither, neither - simply that Neville and Nigel are whatever 1900 calls "hipsters" and are ahead of the curve culturally.  They probably
had a copy of her working copy of the deck even before she met Waite...

or, there's the time machine option to consider as well
 
"By 1893, Smith had moved to Brooklyn to be with her father, where, at the aged of 15, she enrolled at the relatively new Pratt Institute and studied art under the noted artist teacher Arthur Wesley Dow. She graduated four years later, and returning to England in 1899, she became a theatrical designer for a miniature theatre and an illustrator. She joined the Hermetic Order of the Golden Dawn in 1903, and met Waite." (wikipedia)
