Thank you for the request here. There is one image of a close-up of the signature that I can see on my end. Please add a full view of the print and the size.
Thank you for the additional information and for your patience.
The type of signed limited edition vintage print you have is referred to as a woodblock or linocut print; which does differ from an etching. The signature is IW Mason, who is an unlisted artist. Your framed 1925 view in New Hampshire has a high value of $100 - $300 on today's market.
Just checking in to see if you viewed your answer and if you are seeking further assistance?
Please let me know.
