A staged street scene showing a delivery van from what was then the Royal Postal Agency. This type of van went into service in May 1913 and and was used until 1927.
When I turned the card over I was surprised to see this sheet covering the stamps. I haven't seen anything like that before but it worked very well.
Both the sheet and the stamps were franked. Three of the four stamps are Christmas issues.
The one at the bottom right is from 1972 but it's the only one I've been able to identify so far. I will keep looking.
This is a post for Sunday Stamps, now hosted by Violet Sky at "See it on a Postcard!"
