Pottery Planter - Shepherd and Goats - Mystery Mark

Hello Board Friends - I have another piece that has a mark I can't seem to find. It's a planter with a mark that looks like a conjoined HK. It's is about 4 1/2" long and 4 7/8" tall. The HK mark is on the back. There are other marks on the bottom, a mold number 9531 (?) and a number 37 decorator mark (I think). It looks to be Continental European, maybe German or French. If anyone knows anything about it I would be most appreciative. Thank you in advance.

And one misattributed to Hutschtenreuther.

Thank you, INH. I hadn't even considered it was majolica. And I took another look at the planter and realized it has a striker on the side. Maybe a cigar holder? Or just long matches?

 

Spill vase?

 

Apparently there is also a matching shepherdess.
