I got a small number of these some years ago, NIB. looked like wartime cardboard packaging with c'board dividers. wish I'd saved that! outside of mine, I can find none other here or elsewhere, so assume this water tumbler is a very rare WASP accessory. is it? the glass wall is 'hefty,' and the design deeply-cut in and frosted. total 4 pix, first 3 now, last coming directly thanks a lot for all comments guys'n'gals and happy 2019.
