Title: 引蝠圖 (yin3 fú tú)
Translation: Bringing in bats (good luck) painting.

This wall scroll is discounted because of a red signature ghost and a very minor spot (watermark) in the paper.

If you are wondering, red ghost refers to a red shadow of the artist's red signature stamp. This is sometimes ink transfer from a previous painting which happens when the artist signs all of his work at the same time and piles up the paintings before the red ink is dry. It's more common than I would like, and it costs me a lot of money - but I am picky about quality, so my loss is your gain.
