Angkor Wat rubbings 2 (Originals)

I picked these up from a pilot who flew in Vietnam.  He said he got them while at the Angkor Wat Temple around 1969.  They are mint.  Back shows they were framed in Cambodia at that time.  Frames are beautiful, teak and cloth around edges.  They blow me away.  I'm not sure if I should sell them.  Dying pilot told me they are worth thousands.  They are mint.  Stored in bag under a bed for 30 plus years.  I really don't know what I have here except they are original and excellent.
