This was sent to us via email from Ann & Mano. According to them, the owner of this driver’s license was an RAAF personnel, and would have worked on aircrafts almost daily. The Singapore-issued license (1955) is the picture on the left. The picture on the right, however, is a photo of a particular airplane attached to his driving license. Therein lies the mystery!

Was this a common feature for such licenses issued back then? Anyone care to shed some light on this?
