Not great art at all, but I like this modified screenie so here it is.

Originally the VVS didn't fly student lessons in winter, preferring to utilise the easier summer months as potential recruits came through the aeroclubs and passed medicals (Those who did well in medicals were 'persuaded' that flying was the thing for them). Of course, after Barbarossa, all that changed, and flight training went on all year round.
