Lucy had a record album of "Annie Get Your Gun" which she claimed Ethel Merman had autographed for her at a record store 17 years earlier, which would be 1946, when "Annie Get Your Gun" premiered. However, 12-inch long playing record albums weren't introduced until 1953, and furthermore, the album seen in this episode wasn't the original green cover design but a white cover (with a target) that was introduced much later. So the only album Merman could have autographed in 1946 would have been a binder of 10-inch 78 RPM records.
