vintage handmade baskets, lot of coiled basket bowls and trays

Lot of four vintage basket bowls and trays... we know nothing about these except that they're more than 30 years old!

But we do like the big trays (they'd make wonderful trivets for plates), and all four of these pieces look so good together. The largest tray is about 16 1/2" in diameter. All four pieces have a little wear and / or spotting.
