While we're stuck at home and unable to go card-shopping, what a handy thing to have WikiTree's antique postcard collection! E-Cards are found on the Find menu at the top of the page. I just sent my brother a WikiTree E-birthday card. For Easter, there are 49 different cards to choose from.
Just one little request to WikiTree: I'd love it if I could receive a copy of the card I've sent, just as I receive copies of the private WikiTree messages I send.
If anyone has a collection of antique postcards to contribute, I imagine they'd be welcome.
