Why do Top-Aligned Minipages Create a Vertical Margin?

Question

Using the following bit of code, I experience unwanted behaviour.

\documentclass[11pt,a4paper]{letter}

\usepackage[sfdefault]{roboto}
\usepackage[german]{babel}
\usepackage[a4paper, showframe, margin=24mm]{geometry}
\usepackage{graphicx}

\begin{document}

\begin{minipage}[t]{14mm}
\vspace{0pt}
\includegraphics[height=17mm]{Placeholder.pdf}
\end{minipage}
\hfill
\begin{minipage}[t]{100mm}
\flushright
\vspace{0pt}
Lorem Ipsum\\
dolor sit amet\\
consetetur sadipscing elitr
\end{minipage}
\vspace*{50mm}

\today

\end{document}

The result: https://i.stack.imgur.com/PMzu9.png

Where does the vertical space between frame and content of the minipages come from and how can I eliminate it?

I tried these things:

• No \vspace{0pt}. The logo placeholder moves to the frame (where I want it), but the text moves down more.
• \vspace{0pt} only in first minipage. Text moves up to the frame (where I want it), but logo placeholder has the unwanted margin.
• Minipages with given height of 25 mm via \begin{minipage}[t][25mm]{100mm}. No effect.

I've had these issues with minipages for a long time. Maybe I misunderstood something? I'm also grateful for hints on how to achieve what I want with other methods than minipages.

Thanks for your help.

I'd go for your first solution with no \vspace{0pt}. To get the correct image alignment, you can use the valign option from the adjustbox package:

\documentclass[11pt,a4paper]{letter}

\usepackage[sfdefault]{roboto}
\usepackage[german]{babel}
\usepackage[a4paper, showframe, margin=24mm]{geometry}
\usepackage{graphicx}

\usepackage[export]{adjustbox}

\begin{document}

\begin{minipage}[t]{3cm}%
\includegraphics[height=17mm,valign=t]{example-image-duck}
\end{minipage}%
\hfill
\begin{minipage}[t]{100mm}
\flushright
Lorem Ipsum\\
dolor sit amet\\
consetetur sadipscing elitr
\end{minipage}%

\vspace*{50mm}

\today

\end{document}
