Its a pretty little creamer but no way to know who made it unless it is marked !! While they do use trademarks it would be something that one would know !! Most just used a company name !! I think your creamer is probably mid century or about that time period !! I would suggest going to www.replacements.com and use their matching service !! They may be able to find the mfr and the pattern if there is one !! Many just used a number rather than a pattern name !! Could be that the 1211 is the pattern number rather than the mold number !! But that doesn`t help unless you know the company name !! Sorry could be of more help but thats the way it is with these old pottery items !!
Doesn`t look like any kind of a mark at all !! Initials are usually the decorators initials !! That is how they got paid,, they were paid according to the number of items they completed !1 The number is the mold number !!
Can you take a pic of the creamer upright with the lid on ?? Need to see what it looks like !! Likely an import that would have had the sticker where the gold patch is !!
