Very old 5 gallon stoneware jug - possibly a whiskey jug. Excellent condition, no repairs and appear just as they were made. I've had them for years and it's just time to reduce "stuff" in my house. I've seen them on-line for anywhere from $65 to $165 and some of those had significant damage. The "blue heart" with the "5" in it indicates the maker but I don't know who that would be.
