Abstract: Newsbox post support system includes an upright newsbox support member attached to a mailbox support, to which is attached at least one newsbox. A guard member may be included so as to guard the mailbox and/or newsbox(es) from road damage such as caused by plowed snow. The newsbox support system can be fulfilled with a post support comprising a support body having a subsurface contact flange in connection with a post-receiving restraint. The post support is useful to mount and support a post such as that of the mailbox, that of a separately mounted newsbox set and/or for other applications such as a fence, bird feeder or bird bath. The post support can be permanently installed in the ground, or it can be temporarily installed on the ground. The post support and the post can be combined. A weed control collar may be employed with the post.
