I hope that each and everyone of my readers is as well as can be. To cheer myself up – not just in these times – I imagine inviting cherished guests to a party. Because everyone is different, here’s a selection of invitations – I enjoy matching invitations to guests – which one would ensure you’d be ‘delighted to attend’?

Possibly ‘Millar and Lang Ltd’ (originally in Glasgow, later in London, 1903 – 1982).
On the back it just states: โ€˜National Seriesโ€™ ‘Made in Great Britain’
My guess is that this is from the 50’s.. it would be consistent with the 1956 ‘Houseparty Hop’ record (as in the main image). For the music, see further below.
Maker unknown – just ‘7004’ and ‘Made in U.S.A’ on the back
One of my personal favorites – so cute – and the promise of a good cocktail!
Also from the 50s – as the company name changed to ‘Gibson Greeting Cards’ in 1960
Ok, this is, strictly speaking, just for Christmas, but I love the OP-Art, so would send it anytime
… and replace ‘holiday’ with a relevant word. No exact date on the back, my guess is 1960’s (and it’s by Hallmark)
… super-kisch from the 1970s.
Universal Greetings Ltd ‘Printed in England’. All I could find is that the company at some stage was based in Tonbridge, Kent.
a cheeky one…
My guess is that this is from the late 80’s/early 90s. Printed by Rust Craft, but importantly ‘Printed in England’ . A Greeting Card company of that name was listed from 1987 – 1993.
I doubt that there is any connection to Rust Craft, USA.

Well, all we can do at the moment is to reminisce
