Gorgeous Vintage Mid Century 3 Piece Oil

Let me start by saying that we are in no way, art experts. Please ask questions in a timely manner so answers can be obtained. We will answer all questions to the best of our ability, but there are no guarantees. What I can tell you is that this is an amazing mid century piece. It is in phenomenal condition and was just taken off the wall along with other mid century pieces. Please do not judge our ignorance as we just want to match this piece with the appropriate owner(s). Paintings on left and right are 12 1/8 inches across and 36 1/4 inches high. The center painting is 36 1/4 x 36 1/4“.
These paintings will be professionally packaged and shipped. This will likely longer than the five day handling period outlined as we do not live in an area with professional shippers. while researching these paintings we were able to locate one set that were sold online for over $3000. This is the only comp we have to go by. Again, please don’t judge.
We do not accept returns. Once these paintings are sold, they are yours. Please keep that in mind, but buy with confidence. We have sold almost 400 items on eBay and have excellent feedback. International shipping will be considerably higher. These paintings could ship any of the major package carriers, whichever is the most economical.
