Gibraltar Chronicle: Wednesday 8th February 2006
“This is a small print come painting. Some trees in a park. There’s a basis of photography to it. Very beautifully done and a very professional piece of work and probably the most professional in the whole show even though it is the smallest piece. Again the experience is matched to the way in which it is dealt with. It again hits the spot.”

“I liked his two paintings. But the winning one (Mint Tea) was different and genuine in an original way. It had authenticity and it was very promising. There is a language here waiting to be developed.”

“ This is a work in an expressionist style which caught my attention from the start. For me it was the best work with great technical ability. For me the elements in choosing the winner had two aspects both in its technical forte and its power to move me. In this case both these elements fused. It is figurative work which represents a person sleeping which caught my eye in the way the brush was used and in the composition of the light.”

“One of the Rock’s most exciting young artists”

Gibraltar Chronicle: Thursday 15th October 2009
“ His work is fresh and colourful without being too much in your face. He brings to the canvas a certain uniformity in the textures which underpin his creations. I’m convinced that this young man has already made his mark and that he shows great promise is in no doubt. He likes a challenge and who knows where that might lead him to next time. Whatever happens I want to be there and so will you if you have more than a passing interest in Art.”

7 Days: 30th September 2011

"With a host of exhibitions between them it is no wonder that after their initial attempt at putting on a show together in December 2010, and with the success and popularity it obtained, these two young artists are getting together again to host a dual exhibition this autumn."
(Referring to the joint exhibition, 'Beyond 2 Palettes' with Chris-Anne Alcantara)

"Karl Ullger has also made import contributions to the artistic development of Gibraltar"
(A passage extract (page 44) from the Pictorial Autobiography of the artist Mario Finlayson)

Mario Finlayson

Gibraltar Chronicle: Thursday 6th October 2011

"Karl Ullger and Chris Anne Alcantara are firmly established among the leading young artists of Gibraltar with a solid and interesting artistic trajectory behind them. Firmly rooted in realism, Ullger's work provides rich tones of expressionism, depth of colour and dark intensity which gives his paintings a powerful and recognisable style. Both are prized artists in their own right with the potential to make a lasting impact in the art world within and outside our frontiers."
(Referring to the joint exhibition, 'Beyond 2 Palettes' with Chris-Anne Alcantara)

"Two artists with different styles that do complement each other. Their styles are expressive and unique at the same time. Whether being a Karl Ullger or a Chris Anne Alcantara; they are definitely works that must be seen"
(Referring to the joint exhibition, 'Beyond 2 Palettes' with Chris-Anne Alcantara)
