This is so awesome. Didn't know about this until your comment. Thanks so much for sharing. I love how bill lets users use his photographs for the postcards.

I've dabbled with releasing a text-to-postcard service but standard 4x6 prints have kept me pretty busy. I'm doing a postcard experiment of sorts: I commissioned my brother-in-law to create unique monthly art and we're adding a free blank postcard in each shipment. My dog Yoda was the subject in July: https://www.instagram.com/p/CE9qMA-FMVo/
