Bluebird Blue Bird Norcrest Lefton Salt order and Pepper Shaker Ceramic Kitsch Vintage

Product Name: Bluebird Blue Bird Norcrest Lefton Salt order and Pepper Shaker Ceramic Kitsch Vintage
Super desirable vintage anthropomorphic ceramic bluebird blue order bird salt and pepper shakers. I'm having trouble pinning down a definitive maker - if nothing else they are very similar to ones made by Norcrest Japan, although Lefton gets thrown around pretty much on every pair of bluebirds. I would imagine to be from the 1950s or 1960s, stamped Japan. The multi-coloured feathers on these little birdies just add to their cuteness - look at those tail feathers!!! These particular birds stand approx 3 1/4” tall. Open to offers.
