This is a Charles Twelvetrees postcard, published by Edward Gross Co., that says “Ring Twice if You’re Lonesome.” The girl is holding two wedding rings, and wants to get married- ASAP! I like the big bow in her hair and her dress with the big rose on it.
This card isn’t too difficult to find- there is one on eBay right now, which is where I won mine. I have had it in my collection for awhile, and it is just as cute as all of Twelvetrees other cards. This was mailed in 1915.
