Where to find a cheap vintage mirror for a welcome sign?

I would look at good will or salvation army. You might have to paint it but you might be able to find a mirror with that detail on it

Try offerup

Also, if you're near a hobby lobby, check that out

Flea market or goodwill.

Do a search on www.searchtempest.com this is the type of thing people sell after their wedding.

Thrift stores, then you can spray paint it the color you want

A thrift store!!!!!!

I got a my flower girls basket for $1.50!

If you can find a frame you like, you can always spray paint a regular piece of glass with mirror spray paint.

I got a really cute one at hobby lobby and they have 40% off coupons

I just got two at an estate sale for $10 each, try going to estatesales dot net, they usually have pictures posted of the items before you go to them

They have some cute random mirrors at places like Kohls, Home Goods, Marshalls, etc. Try those!

Also, remember you can get a mirror cut to fit any frame.

EBay... And HomeGoods too. I bought vintage mirror trays from eBay, and a new mirror that looks vintage from HomeGoods.

You could check thrift shops or if you have a Ross in your area you can check there also. My Ross has big mirrors for around $40 and you could spray paint them and distress them yourself to get the look you want.

Auctions

Antique stores often sell the frames for cheap and you buy the glass (also cheap).

Check your local Facebook market place! They're all over mine (also on the lookout for something similar)

My mom owns an antique shop

. And they always have tons .. as well as frames . . But I do know thrift stores always have alot too

We looked in antique shops, Goodwill, and Habitat for Humanity retail stores. We needed up finding it at a HFH store for $8!
