Watercolor on paper, 9 1/8" by 6 3/4" inside the mat (14 1/4" by 11 5/8" in its simple green frame), unsigned, the subject a Spanish (most likely) church tower with arched and arcaded breezeways. I've opened this and don't find a signature nor other information. My best guess is that this would be one of the famous buildings in the south of Spain, such as Granada, Sevilla, etc., though I suppose it possible that it could be elsewhere in the Mediterranean region. The top of the tower has a Moorish architecture look to it. The work is of 20th century age, judging from the paper's appearance. Condition is excellent and fresh, with a tiny edge loss visible only under the mat area at lower right. .
