Made in Concrete, Washington.
These are painted with interior enamel (zero/low voc interior paint), and after June 2021 new pieces will include paint from an  expansive new range of professional mediums, acrylics, additives, and "exotics!?"; Beneath at least 2 coats of non-toxic acrylic varnish (Liquitex - used by top art institutions, although they top it off with the same brand of removable varnish), atop 2.5 inch thick, approximately 6ft 8in wide, hollow-core wooden doors (no handle holes, reclaimed/up-cycled) with painted sides. I regularly scrape them early on in the process with a burly scraper, so the finished surfaces are quite tough.

They hang flush to the wall on two screws by two holes in the back. Standard central spacing of the mounts facilitates easy/instant swaps. I'm happy to trade in any piece (even on a yearly basis for a change of scenery/taste) for another as I believe it enhances both the functionality of such large decor, and the creative process. For example; if you purchased a piece for 1000$ and wanted to trade it in for a new one that goes for 1500$ - The new painting would cost 500$. If you wanted to trade between a piece that sold for 1500$ for one selling for 1000$ - No money would change hands, but you'd have a 1500$ credit towards a new one in the future (I done made a spreadsheet). This policy is only effective in the Pacific Northwest of Washington State. 
I feel like I'm just getting started, and committed to exploring imagery towards the abstract/ambient end of the spectrum on this particular substrate for years to come..
Let me know which one's you're considering and I'll make arrangements to swing by for a viewing. Pricing takes into account my current perception of quality, decorative effectiveness/scope/versatility, market, surface area, time spent on the process, mood, etc  Here's the current Price Sheet.
Free delivery and mounting available in the Pacific Northwest (including Yakima;)
Custom/Commissioned Pieces -  I have new "canvas's" on hand 8" x 3.5", and assorted smaller dimensions.
