The card above is one of many produced by WH of Berlin. These
cards all show buildings in Britain (and abroad?) with cut-out windows and
moon, intended to be held up to the light for effect.
This was a postcard is the earliest of the five from the WH Series
currently [July 2004] on this web site. It is
the only one of the five that has an undivided back, as was normal until
1902 when the British Post Office permitted the address and message to
both be written on the same side of the card.
Though the card was probably produced in 1902 or earlier, it was not
posted until May 1903, when it was sent for a halfpenny about five hundred
miles to Penzance in Cornwall.
