These are Dalmatian Pelicans (“Undan Gangsa” in Malay). Two cards are available.  One was mailed in 1991 with Pulau Pinang stamp but only partly legible postmark (Grade: 2, $2) and the other would be a great, mailed card but for an abrasion on the bottom caused by the cancellation machine, not an uncommon problem on Malaysian postcards (Grade: 3, $2).
