特定のタグが「overflow: hidden」をオーバーライドできるようにするにはどうすればよいですか?

<code class="css">/* parent with relative position */
.relative-wrap {
    position: relative;
}

/* container with overflow:hidden (no relative position) */
.overflow-wrap {
    overflow: hidden;
    height: 250px;
    width: 250px;
}

/* image to respect overflow */
.respect-overflow {
    position: relative;
    top: 75px;
    left: 225px;
    height: 50px;
    width: 50px;
}

/* image to overflow */
.no-overflow {
    position: absolute;
    top: 150px;
    left: 225px;
    height: 50px;
    width: 50px;
}</code>
