A quaint relic of a bygone era ?

I went to Portobello Road and my first two car boot sales of the year last weekend. Didn't get much, but one of the items I bought was something I would have snapped up without hesitation a couple of years ago - tonight I listed it on eBay and I'm not even sure I'm going to get my money back. This is how I described it:

This is either a quaint relic of a bygone era of international travel or a useful accessory for the upcoming resumption of international trade - either way, they normally seem to sell at £20 or more including postage, I'm starting low and with no reserve.

What is it? 

( One of these... )

So... what other hitherto-common products may seem dated or outmoded in years to come as a result of Covid etc? Any thoughts?
