This is S.W. Singapore card KK7675, like a mirror image of their card KK7668, but this time it’s only called a mosque, not the “national mosque.”  Whatever.  Two of these are available.  One was mailed with a Negeri Sembilan stamp and illegible postmark in 1990 (Grade: 2, $3) and the other has a red Express Mail sticker affixed, three stamps, mostly legible Sabah postmark (Grade: 1, $5).
