Vintage Mary Humphrey Vase

This is a good haul!..... purchased today actually, I bought it because it was wild and beautiful!....and the tanish drops of color reminded me of pics of a antique Chinese bowl that has those types of drops on them, I knew the vase was more modern....I sat down and took out my magnifying glass to try and make out the signature on the bottom, but the indoor lighting was not enough and the clay is a mottled brown color...but once out doors in the true light...I discovered that it said Humphrey.....so I googled the name and similar pics of vases by Mary Humphrey showed up....the vase is approx 9.5 in ht x 6 in width.......the only thing I know is that Mary Humphrey listed as modernist -?? --(not sure I'm no expert in this area)....she taught ceramics for 28 yrs.......and she does great work!...
