Is the crack on the big one seen on the other side? How wide is the crack? Or is it hairline? Cracks appear when the wood gets dry. I'd put it outdoors (under a shade or a shed, away from sun and elements). The humidity should close it up over time, just keep it away from the sun. If after a few months the crack is still there you'll have to work around it. Thin it, turn it into a drop top over a mahogany body. Yum! Just pour superglue on the cracks, clamp and there!
Or you can just donate it to my stash
