I have longed to buy an ORIGINAL AH Painting for many years and have found these panting on the site linked below. I "believe" them to be original and it appears this is a good site…however, I am only a very novice collector.
Can some of you experienced guys let me know a) if you believe these paintings to be authentic b) are the prices reasonable and c) is this site trustworthy?

Many Thanks in advance if you could let me know asap. Link below;
