Sentiment on an easel

This embossed, die-cut chromolithograph image of an easel accompanied by a yellow rose and a framed verse is glued to a thick die-cut card that is slightly larger than a modern business card. One leg of the easel is truncated. This is from between the pages of a Geburtstagbuch.

I cannot paint thy portrait,
My love, thou art so fair!
But my heart be thy mirror
I hold thine image there!

This may have been a sticker. This is one of the scan-o-rama series of entries.
