Maybe ask for a card shower? Put ad in the Celebrations/Society pages a couple weeks ahead of the date (in the location where she lives and anywhere she might have lived for some length of time) and ask people to send birthday cards to her at an address you provide.
That’s a great idea. I can’t do it in the local paper, however, because she reads it cover to cover on a daily basis. But, I could place an announcement about her party with a picture to run AFTER her birthday.
That’s a good idea.
