Facebook is dipping its toes into the cottage industry of turning digital photos into printed postcard moments.

The social network has today started permitting a small group of members to mail Facebook photos as printed postcards to their social network pals. The feature is powered by mobile-photo-to-keepsake startup Sincerely and began as a hackathon project.

“A few months ago, some engineers built a fun feature that allows people to mail their Facebook photos as a physical postcard to any of their friends on Facebook,” a company spokesperson told VentureBeat. “You can send your own photos to any of your friends or your friends’ photo to them. The front will be the photo and the back you can add a note for your friend, just like a normal postcard.”

Postcard senders do need to pay a small fee, but Facebook is still experimenting with various prices, the representative said.
