The typewriter is a Royal HH standard from 1953.

The Printer’s Apprentice.

One day the young apprentice Jack
Discerned a rare and welcome lack
Of supervision from the master.
And so he started setting down
His thoughts in type. He went to town
Longer and longer, faster and faster,
With many an error, but did he care?
The type was all just sitting there,
And might as well be put to use.
A reader might be slightly dazed:
His sentences were poorly phrased;
His spelling was a little loose.
But Jack was having lots of fun,
And Jack was never really one
To think too hard before he wrote.
He worked all day; he stayed up late,
Composing at a breakneck rate,
Until at ten o’clock, a quote
About the pleasures of the pipe
Used up the very last piece of type.
Next morning, when the news reports
And all the advertising hype
Were ready to be set in type,
The master was quite out of sorts.
