Wondering if anyone can tell me if they recognize the artist of this Japanese woodblock print. The subject is a geisha, there is a seal on the print, and another one on the back lower right corner, and I've provided images of these. Would appreciate any help with this.

The piece in the images below appears to be a woodblock print, but since I haven't removed it from the frame I can't be sure. It depicts a lot of birds in a tree, all of which meld together in places. There is a signature in the upper right corner, and there is a seal there. I'm hoping someone can tell me who the artist is. Thanks for your help.

This is a tempera painting by Russell W. Frost, titled THE SEA. It measures about 39" x 29", and is quite a dramatic scene. Can someone tell me what the value of such a painting might be?

The piece in the images below appears to be a woodblock print, but since I haven't removed it from the frame I can't be sure. It measures about 30" x 24", and depicts a lot of birds in a tree, all of which meld together in places. There is a signature in the upper right corner, and there is a seal there. I'm hoping someone can tell me who the artist is. Thanks for your help.

I have a painting by Alberto De Castro, dated by the artist in 1982, titled SUNDAY SAILING. It measures about 23" x 24". Can someone please let me know what the value of such a painting might be?

These are two original drawings by Seattle artist, and youngest member of the Northwest School, William C. (Apparently his name is not appropriate fro this site, so I hope you know who I'm talking about, the man dies just about a year ago). One is of a seated smoking woman, drawn on the back of a notepad cover, measuring 7.75" x 4.75". The other is a woman doing a handstand on a page from a German psychology text. Hoping someone can tell me what they are worth.

You have posted 6 questions about artists and/or the value of artwork within a very short time frame. There is no one here who is an art expert. All we can do is the same on-line research you can do.

I would bundle up ALL of the artwork and take it to an appraiser. They have both the knowledge and resources which you need.
