Assistance understanding special item in Mankamero

[AdrianB]

Hello all

I apologise if this is a bit off topic but where does art end and food begin ?

At Mankamero 『萬亀楼』restaurant in Kyoto there was in 2010 I think a special 'scroll' 『雪中松図屏風』 of some important on display at times.

I think this is a YouTube video of it:

It would be very helpful to know roughly the significance of this piece and how it relates to Mankamero and their very long history (1722). My very basic Japanese is not helping me at all.

Kind regards

Adrian
