Oil on canvas painting of a landscape waterfront cabin signed in capital letters ROTHMAN. Googling the word Rothman is endless pages. Who this artist with no first name signature?

It's impossible to identify the artist solely based on the last name "ROTHMAN" without more information. There are countless artists with that surname, and even if we could narrow it down to a specific person, it's unlikely to be a well-known name given the lack of a first initial or other identifiers.

To help you find the artist, you could try these steps:

1. Look for other clues on the painting:

* Location: Where was the painting found or purchased? This could help narrow down the artist's potential location.

* Style: Is the style realistic, impressionistic, abstract, etc.?

* Date: Is there any information about the painting's date of creation?

* Subject matter: What does the painting depict? This could be a clue to the artist's interests or region.

2. Check online art databases: Websites like Artnet, MutualArt, and Artprice can be useful for searching for artists by name, style, or subject matter.

3. Consult art experts: Consider reaching out to local art galleries, museums, or art historians for assistance. They might have access to specialized databases or historical archives.

4. Post images online: Sharing images of the painting in art forums or groups might spark recognition from art enthusiasts.

Remember, identifying an unsigned painting is often a challenge, but with some investigation, you might be able to uncover the artist behind the "ROTHMAN" signature.
