These are both limited edition circa 1920's prints by UK artist M. Glyn,
one is print number 48 of 100 printed (the only photo sent of the numbering).
I found other prints by this artist (see photos) with the limited edition pieces
selling for $40 to $60 each on average. The artist is not a listed artist (professional artist)
but did self-publish a lot of prints.
Some sites that I recommend for selling are Offerup.com (local), Varagesale.com (local) , Wanelo.com, http://www.decluttr.com, Bonanza.com, Ioffer.com, Etsy.com,
Ebay and letgo.com (local).
You can also go to invaluable.com or liveauctioneers.com and search their directory for an auction house near you and consign to them.
Please do click the stars now for this one (bonuses are also welcome!), it is very important for me
to get good feedback for answering.
