oblong Mexican ceramic jug/bottle

Here we've got a rather squat oblong jar/jug/vase decorated on both sides. I'm assuming it is intended to be a decorative piece since it is...well . . . "decorated" so nicely with near identical bird/flower-ish designs on both sides, done with great detail using some interesting glazes to give texture to things. (the first 2 pics are one side, pic 3 is the other) The bottom is unglazed and has a signature mark "TENALO S MEXICO" I think...that 2nd letter in the name is hard to make out. It measures about 10" x 4-1/2" x 4-1/2".

CLUES WELCOMED if anybody has more info about it -- I'm nobody's expert in such things?!!
