Spiked Turquoise Vase

Question:
Turquoise vase with tiny charcoal specks. 4ins. at base, 12 finger’s (spikes) around, measuring from 5 ins. to 9 ins. tall. Opening is 4 1/2 ins. across. Not any cracks or dings. It was my grandmother’s, but was my great-great aunt’s before that. She lived in Mc Cook,Neb, and owned & operated the Melkus Motel. ( Pearl & Ed Melkus) Would enjoy knowing more about it. The bottom has Red wing USA M. 1480 on it. Thank’s to anyone who would take the time to respond. Carol Ann

Answer:
Hi Carol, Your "spiked" vase is from 1955, a very good year! Charles Murphy designed a set of 5 bowls with the "spikes" The M is for Murphy. The glaze is fleck nile blue, used for many years. It’s value is around $40.00, but they are hard to find without a broken "spike" thanks, steve n rose
