I also saw a large amber handkerchief vase in hammered texture being sold. Might have been Newark though, from which I returned from on Friday.
But I did find this tray at Newark, which appears to be a very early c.1951 promotional tray. I'm judging this from the diagonally striped border, which can be seen (just) on p.46 Chance Expressions - the promo photo. Whilst this is not clear, the original photo definitely shows an identical border.
