Registration Receipts, Parcel Post and Express Mail

Post Offices issued receipts to the senders of Registered Letters - here are two examples, from 1854 and 1857, the first on white paper, the second on blue.

Parcels could be registered from June 1891.  Here is a Parcel Post label from Bath in the KEVII period.

There were different levels of  'Express' service, the most common being where the mail was sent in the ordinary post to the nearest Express Delivery Office, and were then sent out by special messenger.  This example from August 1922 was to Huntly's Beach Hotel, Weston-super-Mare - the postcard at the bottom shows the location of the Hotel.
