The Open Country of Woman’s and Man’s Heart from The Bride’s Book Of Etiquette (1948).
A preface to the maps reads:
Over a hundred years ago an anonymous young lady of wit and perspicacity mapped the hearts which we reproduce here. While the gentle irony is of her own era, the sentiment is ageless— so we reprint them for the romantics of today to frame for keeps. A choice bit of Victorian litography— originally printed by Kellogg and Thayer.
