Horace Walpole's copy of the death warrant of King Charles I

This is likely the Walpole copy from Strawberry Hill, now in the Milton collection of the Yuko Nii Foundation:

In his home Horace Walpole hung a copy of the warrant for the execution of Charles I with the inscription "Major Charta" and wrote of "the least bad of all murders, that of a King". In 1756, he wrote:

 I am sensible that from the prostitution of patriotism, from the art of ministers who have had the address to exalt the semblance while they depressed the reality of royalty, and from the bent of the education of the young nobility, which verges to French maxims and to a military spirit, nay, from the ascendant which the nobility itself acquires each day in this country, from all these reflections, I am sensible, that prerogative and power have been exceedingly fortified of late within the circle of the palace; and though fluctuating ministers by turns exercise the deposit, yet there it is; and whenever a prince of design and spirit shall sit in the regal chair, he will find a bank, a hoard of power, which he may lay off most fatally against this constitution. [I am] a quiet republican, who does not dislike to see the shadow of monarchy, like Banquo's ghost, fill the empty chair of state, that the ambitious, the murderer, the tyrant, may not aspire to it; in short, who approves the name of a King, when it excludes the essence.

The warrant itself reads as follows:
