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 !!
