Just for the record, I am not answering my own question. The stein in question can be seen in the Reinhold Hanke catalog on The Beer Stein Library. It can also be seen in the Steinzeugkatalog under Character Steins. One from circa 1900 in mint condition can go for $1,000 to $1,200 in a stein auction catalog, but that includes the buyer’s premium. It would probably go for less on ebay considering a lower costs for the seller and buyer.
