Re: sigh! -- well, I thought I'd try offering one of my more labor-intensive (and therefore pricier) paintings on eBay, BUT...it didn't sell. I haven't decided if I'll try again with this piece or if I'll try something that doesn't show the desert.
In the meantime, I just posted these paintings on eBay (here are links for Joshua Tree on the left and Jumbo Rocks on the right). I can ask less for these pieces, and I hope some Mojave desert/Joshua Tree National Park fans will see them and decide they can't live without them.
