Malaysia Frog Stamps - Perf. Flaw

A minor error was recorded on perforation of the 30s (Perf. 12) frog stamp sheet (a single sheet contains 20 stamps in the format of 5x4). The upper horizontal perforation of the second row stamps was shifted one-pin-hole down creating first row stamps with larger size and second row stamps with small size (short of one vertical pin hole). The other three rows are not affected by this flaw.
