Lever House, NY and Researching John Haymson ?

I think that is the signature on this one. Can anyone verify it ? I appreciate your help.

 

It looks like classic 50s wall art. The building was a big deal when it was new. https://en.wikipedia.org/wiki/Lever_House

 

It looks right,but Im pretty sure thats a print. Did you see this? http://johnhaymson.com/

 

Just posting a cropped, enlarged view:

 

The print listed here on Etsy seems less faded (?):

ref=market

It also doesn't have the Lever House wording on it, but that may have been covered up in framing.

 

I do not think, mine is faded as it's behind glass but the sun was glaring in the window when I had time to take pics. It looks like watercolor to me. I sure appreciate all the input

 

I am attaching a photo of my Haymson watercolor with zoom on signature

 

Thank you Danno. Here is another photo showing signature up close. Similar, yet slightly different ....maybe from a different year ? So artist always sign exactly alike ? I know my signature varies

 

Just providing additional info for you I collect sports and hollywood memorabilia and know enough not to trust the signature as much as provenance and context.

 

These items are either from my grandparents or parents home. Some I remember as a child at my grandparents and when they passed, were moved to my parents home. Our home is too small to keep it "all", thus I am researching options. I truly appreciate your input

 

Ahhh. What else do you have??

 

found some Solingen knives last night and a machete. I have tons of papers it seems.... lots more to go
