Here's a houseware that seems to pop up frequently at thrift stores: the Keswick Tray! They are printed cotton and fibre glass trays rimmed with gold or silver edges. The company started in the 1960s and is still producing products today. I'm not sure of the date of these two trays though!
I love the cheery florals and the texture of the fabric through the fibre glass.
It looks like they even take custom orders. Of course they are British made...see post below!
