Nice vtg Dutch Harbor Scene painting signed R. Manseaux Mid Century Modern Style

Fresh from a mid century estate north of Boston is this nice vintage painting by R. Manseaux. It is of a Dutch harbor as evidenced by the flag on the boat and windmill in the background. It is in overall excellent condition with no issues to report. Well done in my opinion in a somewhat abstract, mid century style.

I believe it is oil on canvas with sand added so it has texture but I am not an expert in painting mediums so please don't take that as an absolute. 

Painting has been stapled to a cardboard backing. It is unframed and measures 18” x 24” overall. I would prefer to ship it as is but may be able to remove from the backing and ship rolled in a tube. I don't know if rolling it would cause any damage to the painting so buyer would have to decide their comfort level if they desire it shipped this way. 

It will weigh about 5 lbs packed as is. Local pickup in the Boston area welcome.
