Official stamped paper is a tax, created by Royal Order in 1635, and used continually since then for all public and many private documents in Spain and the hispanic world. Although it is called "stamped paper" it is really printed, consisting of a heading on each of the folios of a folded sheet( aprox.size 17"x12"-43 x 31 cm).The heading may be useful as the information required in your e-mail of dec.9. It consists of three seperate elements, all printed: 1) a shield of the ruling king or queen (later of a nation). 2)The category and value of the "stamp-tax"( varying with the importance of the use). 3) The year or two years of validity ( sometimes restamped). These elements which are easily identified could be incorporated in the data of paper, when apliccable.
