[Avodah] "Mishenichnas Adar Marbin B'simcha"

[SBA]

From: Eli Turkel 
<< Beginning Rosh Chodesh Adar there is a custom to hang a sign in the
home that says "Mishenichnas Adar Marbin B'simcha" 
. Some have the custom to place this sign to cover the "Zecher L'churban
unfinished wall area that many have the custom to retain in their home.
Yalkut Avraham 686, Piskei Tshuvos 686:5 >>  Anyone familar with this
minhag?
>>

Which one?
To hang the Mishenichnas sign? Sure. Plenty do that.

To cover the zecher l'churban? Haven't heard of that one.
