My name is ***** ***** I am here to help with your question.
What is the size?
At your convenience, please send photos.
A complete image of the artwork including frame both front and back (do not remove from frame), a clear in-focus close-up of the signature, and a close-up of the surface so I can see the texture will be ideal.
When taking a clear close-up try using the macro function on your camera. It looks like a small flower icon. This will allow sharper focus at a closer-range.
There may be an +Add Files button or if there is a toolbar with a paperclip icon showing on your board, then follow the steps on this link:
I look forward to seeing the images. If you are unable to send photos right away, that is fine – there is not a time limit here.
