One unique gift idea for your grandma who enjoys ethnographic studies could be a book on anthropology or ethnography, such as "Anthropology: A Global Perspective" by Raymond Scupin or "Cultural Anthropology: A Toolkit for a Global Age" by Kenneth J. Guest.
Alternatively, you could consider a subscription to a cultural or ethnic magazine focused on anthropology, such as Anthropology Today or Cultural Anthropology.
Another idea could be to plan a visit to a nearby museum or exhibit that showcases ethnographic studies. You could present her with tickets to the event, or even plan a special day trip to visit the exhibition together.
You could also consider a unique cultural experience that celebrates ethnic and cultural traditions, such as a dinner at an authentic ethnic restaurant or attending a cultural festival in your area.
Finally, you could give her a personalized ethnographic study journal, where she can document her own observations and interpretations of cultural practices and customs as she travels or reads about them.
Or you can get her a star map with an important date you share.
