Royal Mail Delivery Office

Went along to the post office today to pick up a letter that needed a signature.
Not quite sure what these 'things' are but looked striking against the blue sky. Maybe Postie will let us know!!

The letter turned out to be vouchers for John Lewis from my friend down south for my birthday...I am now able to buy myself that new camera!! Yippee!! Thank you very much Stacey!!! Happy Shopping for me this weekend I think.
