Featured Pewabic Detroit tile marks?

Can anyone date this mark? I'm guessing this is a newer piece, as they are still offering this pattern on their website. However, all of the matching tiles I can find have the year in the center of the mark, instead of the number 110 on mine with a tiny "TM" mark included.

I'm just curious. Thanks!

 

Just guessing, maybe 2013 the 110th year of Pewabic.

 

As good a guess as any - thanks! I see that they did have 110th birthday celebrations, specials, etc. I just found the Contact form link on the bottom of their website, and sent a quick message. I'll update if they get back to me.

 

I have a very small collection of Pewabic tiles as, being a pottery local to me, they can occasionally be found in the thrifts here. Pewabic was able to help me with a mark (different than yours) recently. I look forward to your update.
(None of mine are particularly valuable... but I like 'em!)
