Brown Pottery Crock Identification Help Needed~

[poly777]

Hello all, any info on this 3 gallon brown crock would be appreciated. It looks like it's from Texas to me but I'm no expert on this. Also on the bottom edges seems to be some sort of markings, at first I thought maybe it's just the glaze or from the clay randomly forming it but it does look like a real mark, some sort of picture mark (like a stick figure/X shape and an animal) then next to it with initials (looks like maybe K C or K D?), shown in the 4th photo.

So please if anyone knows who made this, where it came from, year or value would be awesome. Thanks!
