Vintage Ink Blotter.  Cleaning Costs are Important Magnus Chemical Company, Inc.  Garwood New Jersey.  Manufacturers of Railroad Cleaning Compounds and Cleaning Machines. 
Features a funny old car (like a model T, but I don't know my cars)  full of three bearded men and an old woman (I hesitate to say hillbillies, but I am a 7th generation Arkansan and they do look familiar) running down the track with a train coming fast behind it- and the caption below says "Ah don't like this short cut Willy... somethin' tells me it's dangerous." 
From the estate of a former railroad executive- check my shop for more. 
CONDITION:  Vintage.  Good for its age.  Has some discoloration and soiling.  Has some corner bumping, top left corner has a good sized ding.  Has some chipping/ paint loss to the front.  No ink on back, but it does have a good sized (about 1 inch long) rust spot on back.   Email for additonal photos. 
I have other vintage blotters from the same man's estate that I will be listing.
