Sign should be around 29.5 inches across. Hole placement and grommets look OK, but I've not seen one made by I-R (Ingraham-Richardson). The ones I've seen are all marked SPS and then a year date. Not saying this one is fake, I just haven't seen one made by I-R.
I have had this one for about 10 years. My mounting holes are on the top. I am not sure how common the side holes are. I believe my makers mark is on the reverse side so I cannot get to It readily. I believe the maker is Veri Brite.
