Recognize this letter

Online font matching sites suggests this symbol is from Linoscript font or Typo Upright font. I think it is the former, as the spiral in the lower part of the E is a bit different.

In the following image you can see an example of Linoscript (from https://www.linotype.com/45918/linoscript-product.html):

And of Typo Upright (from https://www.linotype.com/1086717/typo-upright-regular-product.html)

In case you have this font installed on your computer, you can use xelatex or lualatex in order to use the symbol in your document.

It also looks very much like TypoUpright BT (originally designed by Morris Fuller Benton in 1905 as a reproduction of the 19th century French Ronde), which can be obtained freely from myfontfree.

Here is a demo with xelatex:

    \documentclass[12pt]{article}
    \usepackage{fontspec}
    \pagestyle{empty}
    \newfontfamily{\uprightcal}{TypoUpright BT}

    \begin{document}%

    Some text.

    \Huge\uprightcal{E}

    \end{document}
