Andrey Karpov and Eugenia Infelitsina held solo exhibition in DISCOVERY ART FAIR FRANKFURT 2019 NOV 01-03

A huge number of people came to the Fair in 3 days. In Frankfurt, It is still the only one art fair in the year. So everyone came.
A lot of people aimed at buying came on Saturday and Sunday, which is not typical of other cities in Germany, such as Berlin and Cologne.
If you look throughout the exhibition, then there are more purchases. 
If you look at the content of the purchased work, then the roll towards decorativeness, as in IKEA.
The more difficult the work in terms of thought, the more difficult it is to sell.
