The store where the content of the signboard is wrong regardless of how

In Japan it is common to see signs of shops that are unusual, but it is a picture of a shop building up a signboard whose contents are wrong regardless of how they look. I do not know exactly where the shops in the signboard are looking at, and it makes me wonder if there are shops selling things that are truly listed on the signboard.

Pictures are as follows.

While wrote "DVD - CD - MP3" on the signboard, the shop looks like a fish shop. Where in the world are the DVDs and CDs? Perhaps, a lot of CDs and DVDs may be displayed in the back.
