Chinese Crackle-Glazed Bowl - Signed, sort of?

here's an interesting bowl i found yesterday. nice crackle-glaze. there is an odd, impressed mark under it, which is covered w/ the thick - oatmealish glaze, and therefore illegible.

there is another side of this which has some odd glaze skipping, so it's definitely not a first-rate piece, but interesting nonetheless.

what do you think?
