The photograph shows overall normal signs of wear. It's complete with caption on the back that reads, 

'Alpine Summer training in the Snow
Parts of the Reichswehr Infantry Regiment No. 19 hold climbing exercises in the Bavarian high alpine region. The planned exercises are made extraordinarily difficult by the sudden arrival of heavy fresh snow. A few days ago, an avalanche even claimed three lives among the Reichswehr climbers. The picture shows the professional saddling of a telephone mule before the ascent of a high mountain patrol'.

In the fall of 1935 the I.Ausbildungs-Bataillon of Inf.Rgt.19 became the I.Bataillon Gebirgsjager Regiment 99 and the II.Ausbildungs-Bataillon of Inf.Rgt.19 became the II.Bataillon Infanterie Regiment 100.
