Anyone know the artist Andrew on BIG mid century painting?

Can someone tell me who 'Andrew' is- the artist of this painting I found yesterday? The painting is Big; at least 4ft
PS - It's painted on board with what looks like cement holding it to the frame?
Thank you

 

I think this is from period of another artist who did big paintings; he also had a school & had his students sign his name to their work to sell?
I am - fairly - sure this was by a listed/known artist; I just can't remember who!

 

I'm thinking both journey's and the one in the link are strictly home decor/ 'factory' type art.

 

Yes, I would agree those are decorative art. Journey's is 1970s.

Debora

 

I kinda like this, it's very 70's (in a good way) and that era is popular regardless of the painter.
Will sell well listed as a MCM item

 

It's an artist from artmaster studios but I can't find anything else on them I have a painting also
