I dont’ know who the artist would be…but regarding the print, I have a Lassan print like what (I believe) you are describing bought from his gallery on Maui.
What we were told when we bought it was, the a certain number of the print is made, and then the artist would touch up each one individually and sign and number each one. I don’t know if that is the case with yours.
I’d love to know if what I was told is correct or a total BS sales pitch.
Numbered prints mean nothing as far as quality. It’s become customary to number them because the uneducated public thinks that a lower number means better quality (and therefore brings more money), but it’s pretty much nonsense. The only thing a number tells you is how large the print edition is. It doesn’t tell you how many production runs there are, however. An artist could make 20 runs of 1000, if he was so inclined, so you need to do the homework to find out if there was only a limited run. Most prints are nearly worthless, although there are exceptions.
I doubt it will be very helpful for the Musee painting. If you go to GIS, in the search box on the right is a camera icon. Click on that and it will say Search By Image. Now you can either paste in a URL of a photo or upload one from your computer and it will compare that image against what it has recorded and displays the closest results it can find. Mouly is pretty modernist and brightly colored so it worked well. If you tried, I dunno, an impressionist landscape you’re going to get mostly photos of greenery.
You can also add search terms to try to narrow the search but I don’t usually play with that.
Artists with marketable reputations will document their print runs and destroy the blocks after they are made to preserve the value of the prints. A friend of mine was swindled buying Dali prints from an unauthorized run of genuine plates slated for destruction after the original print run. I would imagine a mid-tier name like Mouly would attract fewer counterfeiters, and the OP’s certainly looks nice. My WAG is that this one is worth under a thousand dollars.
Clicked on the link; copied the URL from the search line at the top of the page linked to; pasted to the camera icon link; got a message saying it wasn’t a valid image. Perhaps I missed a step.
