Here is a Vintage Friendship POSTCARD Card Oh, Be My Friend, Emerson, Flowers & Gold, 1910
At the front, there is written, or more exactly printed:
"Oh, be my friend, and teach me to be thine - Emerson"
I cannot guarantee that the print is a lithograph as I am not an expert in that matter and I don't know how to recognize this. I can just say that the gold is really very beautiful and the flowers look like die-cut scraps, but they are not, they are printed.
At the back, a note has been written to a friend, it is written with a pencil, very small, it is not obvious to read and understand everything. The post stamp shows that it has been sent from Georgetown, on February 21, at 6pm, 1910, Ohio. There is also a very beautiful green one cent stamp.
