Solid Color Blue Henn Pottery Coffee Mug Rare?

Description

Solid Color Blue Henn Pottery Coffee Mug.  I am not a Henn expert but from the little I know of Henn and Roseville pottery, I've never seen an item produced in a solid color.  Most of their work was done and decorated in a sponge wear design.  Even in doing some research for this listing, I see more and mostly sponge wear items.  So I'm thinking this may be a rare find.
Used and in good condition with vivid colors and graphics.  There is some small scratching on the outside.  See pictures.  Other than that no other visible blemishes, cracks, chips, fading, marks, scratches, scuffs, smudges or stains.  Expect minor surface abrasions and wear to design consistent with age, use and storage. Measures 4-1/2 inches tall by 3-1/2 inches wide.
I want you to love your item and be happy with your purchase!
All items are cleaned before being photographed and listed.
I take great care in photographing, describing and often times researching my items with the hopes they find a nice home and will be treasured by their new owner.  Buyers are responsible for viewing and zooming in all posted pictures and thoroughly reading the item description prior to bidding.  What you see is what you’re buying.  If you have any questions or need more information, please send me a note and I'll be happy to help you as best I can.
While 95% of my items are original and vintage, if you do not see the words, “vintage,” “antique,” or “original” or anything else in the listing title, description or pictures that conveys those characteristics, do not assume the item is any of those things.  As mentioned earlier, drop me a note if you have questions or want to double check on something.
As a majority of my items are vintage, they have been previously owned, used and treasured by others and may have signs of everyday use and minimal imperfections.  Items are sold as is and returns/adjustments are only accepted when there was an error on my part.
I reuse and recycle as much of my shipping materials as possible.  Items are sent using United States Postal Service First Class, Priority or Media Mail services. They are weighed again prior to shipping; If I can get you a cheaper shipping rate after the item is sealed, packaged and ready for shipping, I will do that. The difference will be promptly refunded to the buyer.  Should you find and want to purchase other items I have for sale, I'm always happy to combine shipping.
All payments must be made within 3 days of auction's close unless other arrangements are made via e-mail with the seller.
Thanks for your interest in my item.
