I see no dovetails,, just a simple butt joint !! The construction looks to be the cheapest they could find !! Luan, bottom of drawers and pine secondary wood !!
So that leaves the mark,, which is probably the person who did the painting on this piece !! I do not think any mfr would put their name on an item that was made like this one was !! Although it probably had a stick on label or string tag when it was new !! You might check the bottom for a name but I do not think you will find one !! These things like this were just made to sell and not intended to last very long !! You can still see the sloppy glue applied on the drawer bottom !!
