竹报平安 on your painting means  – wishing peace
It pronounces as zhu2 bao4 ping2 an1
 
竹zhu2 sounds like wish (as in wishing someone good health) zhu4 祝

The bamboo is very resilient throughout the four seasons, and has come to stand for endurance and courage in the face of hardships.

It’s the symbol of a noble and strong character.And people believed that when this plant is burnt it makes a crackling sound and frightens of evil spirits.

In the past , people burn it especially on New Year Eve.
Later, we had firecraker as a replacement.
Nowdays, firecraker and fireworks are set off for celebration e as old customs .
 
 
Another meaning of the word is Bamboo for Safty.
We say 花开富贵 together with 竹报平安 which means Flowers for riches or wealth.
 
The meaning of Safty comes from this :
The 竹（bamboo） is the material to make 竹简 (zhujian), which is used to write letters on.
竹报(zhubao)  is the alias for family letters.
so 竹报平安 refers to the family letter to report safety.

So， your "made it" actually is a 竹报平安.
 
 
Makes sense? Good enough? Whatever?

The charactor next to 竹报平安 is the date : Chinese New Year of 丙卯 —-
丙parameter 1 and 卯 parameter 2. Parameter1 has 12 values and parameter2 has 10 values, the combination of them can count 60 years.
So your painting should be done in 1986 or 1926 or ….
 
The stamp is a little too art, I think it is 竹王 which is supposed to be the name of the painter, meaning Bamboo King.
