Cecile Johnson original watercolor "parade" ?

This is a large original watercolor by Cecile Johnson. I have a receipt showing it was purchased from a company / gallery called "The family jewels" (located in park city UT) in 1990 for $1500.- 

I beleive the painting depicts main street, park city Utah but am uncertain.

It is listed ont he receipt as " original cecile Jhonson watercolor parade".

Any info on the artist, approx. value would be much appreciated. When sold proceeds will go to a family who suffered a completel loss due to fire.

Good
