Italian cheap Della Robbia pottery Majolica

Very Rare Italian Majolica pottery flask cheap or liquor bottle featuring scenes as seen in photos. One side has the baby Christ swaddled in a sheet and the other side has two angles holding up a signed shield. Liquore-Valdema PP. Certosini Firenze is written on this side. I am assuming that this had a cork at one point which it no longer has. Condition is good with no cracks or structural damage. There are some light surface flakes in a few spots which is common with this type of pottery, but this is very minimal. Measures about 5" in diameter and is 5 1/2" tall to the top of the spout.
