High quality, outstanding condition and especially size recommend this portrait of cinematic icon, Sophia Loren. It measures 181.10 in. x 51.18 in., or three times the size of the most relevant Sedlisky comparable recorded on Artprice.com. Depicting English actress, Julie Christie, this work measures 58 ¼ in. x 63 in. and sold for $1,204 on 4/18/1996 at Bruun Rasmussen, Vejle, Denmark. (Unfortunately, Artprice.com does illustrate the Christie portrait on its website.) Additionally, Jennmaur Gallery (as of October 8, 2012) was offering a Sedlisky portrait of Yuri Gagarin, the celebrated Soviet cosmonaut, for a price “in excess of $10,000” (per the Gallery's price key). It was illustrated and described as follows:

“Ivan Sedlisky (Czech 1926- ?) “Flight to the Stars” Portrait of Russian cosmonaut Jurij Aleksejevi Gagarin, the first person in space, and to orbit the earth. Oil on canvas dated 1958. Dimensions: h=44 in, w=57 in, frame w=4 ¾ in”

In light of this information and analysis, presale estimates in the range of $4,000-6,000 are both reasonable and justified.
