Soviet original patch chevron with Lenin

Description

Original soviet patch( chevron) with Lenin.
"All-Union communist subbotnik".
Subbotnik was day of volunteer unpaid work on weekends after the October Revolution, though the word itself is derived from Cуббо́та (Subbota for Saturday).
The tradition is continued in modern Russia and some other former Soviet Republics. Subbotniks are mostly organized for cleaning the streets of garbage, fixing public amenities, collecting recyclable material, and other community services.
