This painting originally appeared on the cover of <i>Parents</i> magazine in October 1930. <i>Parents</i> then sold the rights to <a href="https://en.wikipedia.org/wiki/Gerlach_Barklow_Co." class="extiw" title="en:Gerlach Barklow Co.">Gerlach Barklow</a>.<br>One of its artists (not Martin) changed the lettering to "Theory of Relativity," and added the title "Oh Yeah!" The latter is extremely tiny and nearly impossible to spot.<br>Nonetheless, it's in black type under the "iv" in Relativity.
