Any chance someone has an opinion on this Mel Blanc signature. What's throwing me off a little is the lack of the loop in the "M" but maybe he signed differently in his early days, I don't know.
The moment I saw it, I knew it wasn't Mel's based on the same reasons listed below. Individuals of Mel's generation were usually taught in school when writing in script to use a capital "E." I've seen it used in Judy Garland inscriptions, also the Duesenberg Car Company used capital E's.
