Madonna With Baby Jesus Painting

Wooden board painted on both sides. I don't see any skills but wonder if we can figure the signature?
Thanks

 

looks like MICAL to me

 

I see the Mical too, but I see a Z conjoined with the M.

I think the Madonna is very pretty. Simple, maybe even primitive, but sweet.

 

These may be copies of Christmas cards, or something similar. They'd look nice hung up for Christmas, regardless.
