As I start to wade my way through the project this morning at about 10 minutes in I have come across this Summons Letter for British Guiana dated 1891.
It states that Margaret Burus of New Amsterdam kept a dog to which she did not have the required license and that she is to appear in court at 10.30 on the 1st of July 1891.
It has with it a 1 Dollar Black revenue stamp and a summary Jurisdiction stamp. The 1 Dollar Black stamp is said to be rare according to Google sources but its value does not reflect that fact.
Still an interesting document from the past, and if anyone knows more about this please leave a comment below.
