This is the logo of the Communist Party of Germany, which was formed in the late 1910s, from Liebknecht and Rosa's Spartacist League. I have slightly modified the logo to make the hammer and sickle logo appear merged, unlike the original KPD logo.
KPD free icon was designed by KCJV for icons Png and presented to its users.
