Serious question, I just read that some old hand-drawn blueprints from the 1950s can be worth over $2,000 to collectors.

I found this out in an article about architectural archives while looking up something else. It said original ink-on-linen drawings for famous buildings can sell for a lot. On one side, it makes sense as historical art. On the other, it feels weird to put a price on what was just our job back then. I've got a box of my granddad's old utility plans from Detroit, but they're definitely not famous. Has anyone else come across this or know what makes a drawing valuable?

Check if those utility plans show any famous buildings or neighborhoods from that era? Sometimes the value is in the details of a city that's changed a lot. What condition are they in, and are they signed by the engineer? That stuff matters to collectors.

My buddy found a sewer plan signed by the city engineer, sold it for a ton!

Wow, I read that signatures can triple a plan's value if they're from a known architect.
