The Serrane Guide offers the following notes on the attributes of the original stamps:
The stamps are 18 1/2 x 23 mm in size.
The lettering, corner ornaments, and lower frame line breaks are the same as those of the Tuscany Lion issues.
There is a dot after the value abbreviation.
The shield has five vertical shade lines in each quarter.
None of the shade lines are joined to their neighbors.
The vertical beam of the cross is under the "T", a little to the left of the letter's axis.
There are five jewels in the band of the crown.
On the 1 - 20 C. denomination stamps, the value inscription almost touches the lower frame line.
The word "FRANCOBOLLO" is printed as ONE word, not TWO.
The paper is grayish white, not yellowish.
