Vernacular concrete markers

I've mentioned this is a special interest so thought I'd put up a few examples. Both are from the Buffalo River area in northern Arkansas. The first one is from the Canaan Cemetery near Marshall. It was designed to hold a photo.
Unfortunately, as is true of almost all grave markers that incorporated a frame meant to hold anything printed on paper, the photograph has suffered so much water damage that it's now almost completely obliterated.

The second marker is from the Silver Hill Cemetery located just outside the boundary for Buffalo National River off US-65. It, too, was designed to hold a photo or plaque, which was either never mounted in place or has since been removed.

The Canaan Cemetery is also notable for its amazing two-tier table graves. Unlike the table graves common farther south in Louisiana, these are strictly false vaults. Actual interments were in-ground, not above.
