The elephant fabric in your found quilt looks like a recent design, so the quilt couldn't have been that old before it was discarded. I once found two identical "house" quilts in different colorways for only $2.50 each at a thrift shop. They looked like samples from a quilt class - never used, never washed. I snapped them up so fast because I've always wanted to make a house quilt and just thought they are so complicated.
