I am not sure if this time in our history is particular challenging, or if it just seems that way because today we hear about all of the bad things that are happening all over the world in real time. This lioness art with the lion and lamb sharing a tender moment, is a balm for what seems to be a challenging period in time. A symbol if you like of harmony and peace. OR, the lion in this lioness meme, could just really LOVE lamb.
We all come at the world from a different angle, we interpret each situation from our own unique perspective. However you as the viewer want to look at this serigraph, your perspective is the right one. If you want to see this as a representation of the idea that everybody loves everybody, you are absolutely correct. If like me you have a somewhat twisted sense of humour, loving lamb could have more than one meaning, simultaneously.
