The former National Postal Museum was in part established to house the collection. Today, The Postal Museum has taken over responsibility for caring and developing access to the Phillips Collection.
The Phillips Collection is an essential resource for the understanding of postage stamps and philatelic research. It contains the world’s very first, first day cover – that of the Penny Black. It also includes 1839 Treasury Essays for pre-paid postage, Rowland Hill letters and unique proofs and studies of stamps such as the Twopenny Blue and the Penny Red.
The Penny Black Changed the World project in 2005-2006 – supported by the Heritage Lottery Fund has allowed for all 45 volumes of the Phillips Collection to be digitised.
