4 Queens Painting By JHB 10-24-95 Any Ideas?

Hello everyone, here's a group of paintings I found at the Vietnam Veterans Thrift store back in 2005. I've had them packed away in my attic since then and finally am trying to research who the artist may be. They are painted on framed canvas and measure 20"x16". I've exhausted every method of search I have and am wondering if anyone has any ideas on the artist. As you can see each is dated and signed by what looks like JHB along with a copyright mark Any comments are deeply appreciated. Best to all.
