The thing to the left is the symbol for amnesty for the prisoners of the Basque independence movement. See another mural with the same symbol and read more about it here: https://basquemurals.wordpress.com/2016/02/14/the-prisoners/
The symbol to the right is a “lauburu” or Basque cross: https://en.wikipedia.org/wiki/Lauburu
