Hi! I have this Cream of Wheat advertising poster 'where the mail goes cream of wheat goes' I'm wondering if anyone knows the date or any other info on this poster? I believe the original was an oil painting in the early/mid 1900s. This one says 'litho in USA' bottom left so a reproduction from some point but I can't find any info or any similar posters that have the brown border and litho in usa printed.

I was able to find an early version with a green border (as opposed to brown) but no 'litho in usa' printed on the bottom.

If anyone has any info it would be appreciated, thanks!
