Read the profile
Look at the relationship between the neck, spout, handle and body. Record maximum width as well as height; a tall pitcher may need substantial shelf depth. Leave enough space to lift it without striking the shelf above. Compare the object with its intended neighbours rather than treating a close-up product image as a sense of scale.
Document the workshop reference
Blanot appeared in the former address. That reference is not a substitute for a documented workshop mark or provenance. Request a clear underside photograph and keep any proposed reading of a signature alongside the original image. Uncertain letters should remain uncertain rather than becoming a firm attribution through repetition.
Check vulnerable areas and choose the use
Examine the handle joins, spout and foot, and ask about repairs. A variation in glaze is not automatically damage, but a deep line cannot be evaluated from a distant image. If the pitcher will hold water, establish whether that use has been assessed. For a purely decorative grouping, relate its volume to lower objects and keep a photograph of the chosen arrangement.
