Identification Help

[elks]

OK I know this not a 47 or newer Chevy, but this board has lots of car guys. If the post needs to be moved to another place please do so. I just want lots of people to see this and maybe someone can give us more details...

Attached are some quick photos I took today. One of my high school students brought in a sheet of blue prints today. He said he had something really cool for me to see and that of all the teachers in the school I would appreciate it the most.

So he digs into his back pack and pulls out the sheet below. It definitely looks old and is in pretty good shape. I wished I could tell him the car/manufactureer etc. But the information box is blacked out. All it had on it was a date of sometime in 1919.... Here are some pics, I am pretty certain the paper is original and has been around a long time. What do you think? All he knows is his grandpa gave it to him...



A closer look at the car:


And here you can see how the information area had been blanked out:


I told him at the very least to get the documents professionally sealed up and protected. I am certain that not many prints from those years have survived that long in good shape.

What do you think? Where might we find more answers?
