nothing strange about it.  ALL US model vanagon westys have that sticker on their right front door.   if yours is missing it was removed by some PO or the van was repainted.

Subject: Strange place for an identification plate on 91 Vanagon.

My vanagon has it's Identification Plate on the outside of the 
passenger door. I know this is not common but am wondering if anyone 
else has seen this before? My Van spent most of it's life in Japan, 
(imported only a year ago into N.America) and can only assume that 
this is a regulation in Japan for foreign vehicles!?!
