Antonio Lopez art - watercolor?

Hi everyone,
I found this piece by Antonio Lopez at a local thrift store (I went to early before my estate sale started!).
Googling & image search showed me it's by Antonio Lopez, who did a lot of fashion arr for magazines.
An image search turned up others like mine, but those were posters with the signature at bottom center in the same place on all of them - i can't find another like mine!
I also don't see any pixels looking at it with a magnifying glass, not even in the signature where you can usually see them better if it's a print.
What do I have?
Thank you, any help is greatly appreciated!
