Familiar faces and artwork on Mexican Banknotes

I was excited to collect my Mexican currency and to find familiar faces on the 500 Peso notes! I'm always interested to know who's on my money but often the faces and places portrayed on foreign notes in particular are unfamiliar, as with the other values of this currency which will require further research.

Artists Frida Kahlo and her husband Diego Rivera are shown here together with  their famous artworks.

 Diego Rivera's painting  of a nude with Cala Lilies is a subject which he painted  many times. 

The painting shown below is The Love Embrace of the Universe, the Earth (Mexico), Myself, Diego and Senor Xolotl, painted in 1949 by Frida Kahlo. and appears on the reverse of the note .  The picture contains elements from ancient Mexican mythology, including day and night, the sun and moon and the earth goddess cihuacoatl.  One of Frida's favourite pets was a dog which also represents Senor  Xolotl, a Itzcuintli dog,  a being who guards the underworld.  She was very maternal towards her husband Diego  and said she wanted to hold him in her arms like a new-born baby, as in this painting.
