<p>A fascinating photo acquired from a Slovakian auction.  High female density , with some glamorous and some very short participants.Thanks to @tatraskoda (comment below) I can label this with absolute certainty as a Praga Alfa, as seen also in <a rel="nofollow" class="external text" href="https://www.flickr.com/photos/skitmeister/4099235110/">this Flickr photo by</a> @skitmeister.

The <a href="https://en.wikipedia.org/wiki/en:Praga_(company)" class="extiw" title="w:en:Praga (company)">Prage Alfa</a> was built between 1913 and 1942. The firm was originally a partnership between the Českomoravská továrna na stroje v Praze or the First Bohemian-Moravian Machine Factory and František Ringhoffer briefly before becoming Praga in 1909, and being merged with   ČKD in 1929, although the Praga name carried on.
