I thought this rather nice grouping of Kaiser Alexander Garde-Grenadier-Regiment Nr. 1 officers would be of interest. I came across the photo in a Russian language military magazine (Zeughaus) which had it captioned as a group of officers of KAGGR Nr. 1 at Theatre Square in Moscow in May 1896.The date was clearly wrong as all of these gentlemen are wearing the 1897 Prussian centenary medal. A bit of digging around revealed the occasion, the officers pictured and date: 28 August 1898 at Theatre Square Moscow for the unveiling ceremony of the memorial to Emperor Alexander II.
