24Mashburn, W. E. (Oil) - Scanlan Fine Artist
Five years ago, I participated in an auction of works by famous painters related to the sea that had been stored for a long time by a boat repair shop in Monroe, Washington. I purchased "painted by W.E. Mashburn in 1979). Each unique number was stored in a round airtight container. You can inquire at the author's website listed above.
I won the bid for 15 unique numbers, each with a unique number. Of course , the storage condition is 100% perfect .
