Does anyone know what this is?

Picked up a cabinet that my daughter purchased and brought it home. Needs work but my daughter is the one to do it.

When I got it home I noticed this doohickey on and between the upper doors. Does anyone know what it is. Two pictures, one close up and one full blown.

Good job Chris. I looked but did not figure it out.
