Two of these larger (5″ x 7″) cards are available.  One was mailed in 1990 with stamp and just part of a postmark, a bit of abrasion on the reverse, and postmark smudging on the front (Grade: 3, $3.50).  The other comes from Kukup, Johor, with commemorative wasp stamp and full, very large postmark but also with lots of white correctional fluid on the reverse (Grade: 4, $3.50).
