It was 26th December 1983 when I was helping my mum bag up wrapping paper when I noticed the two clear stands stuck to the internal cardboard packaging from my Star Destroyer Playset just as they were getting put into a black bin bag.
For years I was worried that those stands were stuck to packaging in all the larger SW sets and I hadn't noticed them. Thankfully someone invented the internet years later and I discovered I never missed anything.
