The Light Side of the Bulb

"The light side of the Bulb" a play on words to remember a very beautiful album released in 1973.
In this case we are not talking about the dark side but about the light side... that of my Bulb.
My Bulb which when turned on gives off white light and when turned off and is crossed by the sun, refracts the rainbow.
Seven beautiful colors that are projected towards people with the aim of bringing positivity and joy.
My wish is for peace throughout the world.

Look carefully at the photographs: for some travel cups and mugs you can choose the handle you prefer.
