Marvel Universe Trading Cards Series II ad (1990).
Daenerys, mere des dragons, by Alphonse Mucha
Not really related to the Marvel 1980s, but had to share this lovely piece…
It is not physically or temporally possible for Alphonse Mucha to have done this. Definitely an homage to Mucha, but Game of Thrones was put on HBO about 70 years after Mucha passed away in 1939.
Thanks for the correction. It was done by Elin Jonsson, in the style of Mucha!
