The stamps are identical, but where the single stamps are in a square frame, the stamps on the sheet are just the heptagonal stamps, without square frame.
Once out of the frame, you can't see where the stamps came from, the sheet or the single stamps.
Next to the 7 stamps on the sheet, an additional monogram of the King is added, as well as '๘๔'.
This is 84 in Thai language. The 7th Cycle ( 7 x 12) birthday anniversary.
