If Baltfan is correct in deciphering that text, this might be a member of a prominent family. Mrs. John Douglass Wade, Baltimore, Maryland, granddaughter of Louisa Airey Gilmor (Mrs Samuel Owings Hoffman), married May 9, 1826, hence the 100 years old comment.

lindab is quite right... the fashions of the ladies on the fan are from around 1840-1850, not the 1820's. You can see this especially on the woman sitting on the bank to the right.
A few clues... The 1820's sleeve was frequently fitted through the arm, sometimes with a small puff at the top, where these sleeves are fitted in the upper arm and bell out at the wrists, a style that developed into the "Pagoda" sleeve of 1860's. The 1820's skirts were high waisted and a-line with more fullness captured at the center back, where these skirts are natural waisted and clearly full, almost dome-shaped, heading towards the large crinoline hoop skirts.
Of course, since this is 1927, the note taker could have been off just fifteen years, and this fan might be from 1842. Possible...

Appears to be conveying a vaguely religious theme, perhaps a deceased soul being borne to the other side of the river where it's received by its former loved ones? The prone figure has a death's head while the one in the center is the only one looking heavenward and with a halo around her head, the soul of the deceased.

The precision of the name vs the rest of the script makes this look to be a marked up calling card.

Why would you take your antique fan collection on a camping trip?

The ladies illustrated on the beautiful fan are wearing hoop skirts and hairstyles from the 1850s at the very earliest, so in 1927 it would have been at most 70+ years old. The girl, however, is charming, and I love it that she's wearing dress shoes and stockings on a camping trip.

[This looks like the 1820s to me. - Dave]

There were many designs for her to choose from, with and without rhinestones, and this looks like the one she chose.

The fan is fine, but the airplane on her neck is awesome!

I that a "Spirit of St.Louis" pin she's wearing?

Just noticed the airplane pin at her collar.

A possible clue to the lady. She might have liked flying or fliers, judging by the airplane pin at her throat.
