Cube

I don’t know if any of you recognise these bricks.
They were made by Tupperware back in the 70s. They had a range of toys for children. All as well made as their food containers.
I still have quite a few which Jude enjoys playing with now.
These bricks snap open and then you can join them together to make all sorts of shapes.
Just three colours. Red, Yellow and Blue.
As today’s mono challenge is cube I thought they would fit the bill. just changed the colour to b & w.
