Probably listening to her favourite record. A joke which I heard at prep school immediately after her accession to the throne and which I won't repeat here. Wham, bang and thank you Mam!
By now I should hope she's on her third G and T after the tiring business of opening a so-called "new" railway in Scotland. Pity she didn't make the same mistake as Mr Huskisson.
She looks about 17 there, bless her, our 'Elizabeth 1st'. She's certainly had to maintain her public regal demeanour over the years - quite an extraordinary feat in itself.
I should hope she's sitting on a comfy sofa with her feet up, a glass of sherry in hand thinking, "Blimey, hasn't time flown". And, technically, the stamp is wrong ... should really say second.
