I was asked about a painting I posted a photo of. The painting was given to my wife and I as a wedding present in 1978.
It isn't really a painting rather a daubing, the work has been created using a scalpel/spatula to apply the oil paint thickly to the canvas. The paint is in many layers in some places and in others appears to have been brushed over.
There are pieces of black canvas where I think the paint was not applied.
About 2 years ago I was concerned for the paint and applied an acrylic spray paint to the surface. I had not been cleaned before I did this.
The spray paint is similar to what I am using to protect my high quality prints from my photography.
The url to the photo is below
If interested or wanting more detail I can take high quality photos of sections of the painting.
