Hi Viktoria
The hand written dedication "In that rich earth a richer dust contained" has been taken as a part quote from 'The Soldier' by Rupert Brooke, his verse reads “In that rich earth a richer dust concealed”
Rupert Brookes Poem 'The Soldier' was the last in a sonnet sequence entitled '1914'. they were first published in January of 1915
On April 4, 1915, Dean Inge of St. Paul's Cathedral read a sonnet from the pulpit as part of his Easter Sunday sermon. The sermon was published in The Times the next day, so my thoughts would be, that the picture was dedicated then framed, after April 4th 1915.
The Framed Photograph shows Howard Avenel Bligh St George’s original Grave which was prepared with a lot of thought, kindness and respect, it had a Celtic cross with his full name on it, a boundry of white painted stones and 6 pillars set inside the stones each attached to it’s neighbour by a length of chain, the cross and plot residing within the pillars, the soldier leaning over it tending the Plot within, was an incredibly thoughtful touch, to the photograph, this was a well loved young officer, and I believe his brother officers paid tribute to him in, creating this comfort for his Mother, as Jerry’s book states, The Church which is also shown in the photograph and the Cemetery were shelled, destroying the church and this Grave.
