Michelle, an interesting cup. No saucer? Certainly transferware, not necessarily Irish. The center pattern in the cup appears to include Hebrew (???) text above the beehive (???) or other item. We can look into this, but in the meantime, are you a TCC member, or even if not, for $10 for 24 hours you can search our extensive database yourself. No guarantees we have this pattern yet, as many patterns remain to be documented!
