I have a bunch of old slate shingles that I am selling for $4 each (full size), $2 half/partial sizes. Full sizes vary, 14” x 14” and 16” x 12” are the two most common, I believe. Our house was built in 1897, and they may have been original to the house. The shed and garage still have slate shingles. Great for art projects or other creative endeavors. The painted piece is an example of what you can do, it was with the shingles. I would consider selling but may want to keep it with the house. Please email if interested! My name is Ben. Thanks!
