nest of handmade painted studio pottery bowls, rustic clay graduated colors & sizes stack

Stack of nesting bowls signed Lynne Lefton - these are nicely made, though we haven't been able to track down any info about this artist. 70s or 80s vintage?

These range in size from a bit over 5" to 9" in diameter. All have a few little glaze chips to the rims, none have cracks or serious chips.
