I am going to try one more time to post the photographs of the paintings for which I am hoping to receive your most excellent assistance with the translations of their individual signatures. Rather than attach them onto the end of my previously failed post, it seemed a better idea to simply start anew. I know that there are likely to be several ideas on each signature, which is why I went head and posted an image of the painting each belongs to, as well.
