hi Anne - certainly they sound legit, especially with those shiny feet. Make yourself some caramels (from packet mix) with enough for two glasses - place in fridge and when cold and with the consistency of blancmange, add just a little vanilla ice cream ................ heaven.

then phone me to come and share.
I've come across lots of these Inwald pieces over the past ten years - the large water jugs still pop quite commonly here (there seem to be two or three different designs) - I have a claret jug I bought from Andy you know who from the Antiques Road Show. Did once start out to collect as many shapes as poss., but like so many things got bored and gave up. Will try and remember to take photos of those I have and add them to the Board.
If you ever find the table lamp (shown in Miller's) buy it for me as a birthday present, please.

But I like these sweets - and don't believe they're that common.
