Woot! Thank you, Tadashya!
I'm pretty sure it's "Home Sweet Home" by Varillo & Montana in the July 1990 issue. Sure can't find anything online on them but at least I have a detailed item to look for at the collectibles shops.
P.S. - I could have sworn it was a Royo painting but so many artists try to emulate him that to my untrained eye it's hard to tell the difference sometimes.
