need info on architectual drawings found in an attic

[gaga4toyz]

I found these old architectual drawings and a map of St. Louis dated 1924 in an old attic. I think these look incredible. It must have took alot of time to do this stuff by hand. The writeing on the map looks realy cool as well. Is there any value to these items?

They're neat !!!

Take them to your local library and see what they say.

The town might be interested in them for historic value.

The street lay-out is awesome. I would frame it and sell it. The house plans are cool if you know the address and the house is still standing.

The street layout is probably pretty valuable, like a map.

pretty darn cool

the street layout is the platt that the tax office uses to assign taxable properties to the responsible parties. You can go to the area tax office and try to match it up to see if it is a copy (even if hand made) or if they even have that particular drawing.

Not sure if there is a big market for vintage house plans, unless they are from a prominent architect. See if there is a name of the architect or draftsman on the drawing and look that up.

As an Architect I used to draw like that. These are known as Blueline or Blackline prints. The originals would have been drawn on velum paper or even linen. Back when these were drawn they would have been printed as blueprints. The background would have been blue and the lines and text would have been white. Those drawings were probably printed in the 70's or later. Not that valuable. Original blueprints would be worth more. The original pen or pencil drawings would be worth the most. If it was a local landmark building such as a theater, courthouse or architecturally significant building you could probably sell them.

The street map is typical of the maps found in the courthouse records of each district. These are plot plans. An out line of the plots in each district. No real value unless the official records don't exist.

The house plan would be a keepsake for the owner of the home that was built from them. Not much of a market for them otherwise.

If you like them you could frame and display them but the paper will yellow quickly when exposed to light. The paper these are printed on is kept in the dark. The original drawing is placed on top and exposed to a bright light than an ammonia wash to remove the chemicals. Similar to printing a photograph.

Here are examples of Blueprints, Blackprints, Bluelines and Blacklines of the same car. All are commonly called Blueprints.

My father studied personally with Frank Lloyd Wright considered the greatest architect in the world and I can't sell Dad's plans for nothing...

Yeah, there's not a huge market for run of the mill blueprints...unless it's for a real famous historical built like the Titanic...or something like that.
