Perforation error in Singapore 2010 Year of Tiger 1st Local NVI

It is very rare to find major errors in modern Singapore stamp issues. This se-tenant sheet of 10 of the Singapore 2010 Year of Tiger 1st Local NVI stamp containing extra perforation on the right column just appeared on an on-line auction site. This error looks like an outcome of a shifted perforation process; this might mean the existence of another sheet of 10 of the same stamp, which is perforated only on the left column, and has no perforation on the right column!

Singapore 2010 Festivals

Singapore Post released the biennale festivals stamps on 20 October 2010. These stamps depict the festivals celebrated by the 4 main races in Singapore - Chinese New Year for the Chinese, Hari Raya Haji/Puasa for the Malays, Deepavali or Diwali for the Indians and for the Eurasians who are mostly Christians, Christmas. There are 2 stamps for each festival, the 1st local one for local addressee and the 55-cent post card rate for posting overseas; for many years Singapore Post has implemented special rates for posting greeting cards weighing not more than 40g at 55 cents. The 55-cent stamps are printed with metal foil on part of their designs, giving a holographic effect for the twinkling festival mood. This year, a collector's sheet is also released, containing 8 stamps with the same designs, but with the 1st local stamps face values changed to S$1.10, and printed with metal foil on some parts of the design, like the 55-cent stamps.

The 2nd local stamp features the Singapore Rhododendron (Melastoma malabathricum), a common plant with flowers that also last only a day; the plant is a host for caterpillars of butterflies like the Common Sailor (Neptis hylas) and the Grey Count (Tanaecia lapidea). The 1st local stamp was also released as self-adhesives in booklets of 10 stamps and sheets of 20 stamps.
