Antique Mexico Hand-Painted Planter…

My grandmother had this planter over 80 years she stated to me; I’m 44 years old and this planter has been with my grandmother my entire life. My grandmother probably told me 40 years ago how it was obtained/its history, but sadly, I am unable to recall any details. All I definitely know is the planter is very old. Markings indicate the planter is from Mexico both on the bottom of planter and inside the planter. Heavy crazing, lines, discoloration to areas of the planter but do not note any chipping or cracks/breaks. Outside of planter is painted blue with flower design and when your hand glides over some parts of the vase, specifically the area painted with blue flowers, rough areas are felt / raised spots (like air bubbles prior to drying or how the planter actually dried). Circumference approx 5.5” at top opening, length approx 10” with drainage hole… Any questions, please ask… Enjoy…🩵🍂.
