Singapore
"Enclosures are not Permitted"

This aerogramme (Wiegand no. 61) was sent to France on 17 AUG 98. Enclosures are not allowed for aerogrammes. Hence, the postal authorities in Singapore applied the boxed h/s "Enclosures are not / Permitted". 

Accordingly, the aerogramme was taxed as a short paid airmail letter.
