A handwritten note included in the post reads: "We welcome you to share in our joy. Thank you for respecting our privacy during this beautiful time in our lives." The note is signed "The Carter Family."
Boasting a full head of dark hair, baby Blue Ivy is photographed sleeping in both her famous parents' arms.
The photos come just a few days after Beyonce made her first post-pregnancy appearance at Jay-Z's Carnegie Hall concert.
Sharing such photos for free is an unusual move for a high-profile couple like Beyonce and Jay-Z, who have probably been offered millions of dollars by publications seeking to debut celebrity-baby pictures. (Angelina Jolie and Brad Pitt were reportedly paid $11 million - $15 million for photos of their twins Knox and Vivienne Jolie-Pitt in 2008.) Seemingly, the Carters are saying no to hoopla around images of their daughter.
