[Edmond Becquerel & others; International Congress on Weights, Measures and Coins June 1867
One page from an Album, 28 x 23cm, edges frayed, some staining but signatures clear. A vandal has however cut out and detached the signature of the President, Prince Napoleon and Mathiew[?], President of Committee, so lost. Thirty six distinguished signatories survive, led by Edmond Becquerel and including John P. Kennedy, Edmund K, Muspratt, etc - presumably leaders in the field. SEE Image.
