[1] The Monochrome Proofs were done on thin cards and in black and white by Walsall Security Printers of London UK, and were used to check the design. The perforations on the proof are only simulated.
The monochrome proofs were produced, in amounts of 20, after the Cromalin one, then sent to Tonga for the officials to check. When accepted, they were sent to stamp magazines to illustrate the upcoming new issues.
[2] The he Plate Proofs printed one sheet of plate proofs first, this sheet was taken for checking and approval by Walsall Security Printers company and the officials of Tonga.
After it passed the necessary checks, this imperforated proof sheet was placed in the printers archives and was left imperforated. All other sheets issued were perforated.
The Tongan plate proofs are genuine proofs done by the printers for checking purposes then kept until recently in the printers' archives.
[3] The "SPECIMEN" overprint in black was the normal specimen overprint done for most sets ot Tonga from 1981 to 1997.
[4]Tonga did not issue any imperforate stamps from this set, the only imperforates known are genuine plate proofs, and come from the Walsall Security Printers archives.
