An old, dusty photo [STAMP]

It's an an old photo with a wooden photo frame, the words "First Day home!" etched into it. The glass pane on the front has a crack running across it.
On the back, there's a note:
"A photo taken by surprise, but still a happy one. The day we finally brought our little one home after a week under Doctor Audino's careful watch. Out of all the treasures we've found in our years of adventuring, you're the most precious by far. Welcome to the world Uva, we can't wait to watch you grow."
It seems to be signed by three different names, though they're all faded.
